FAQ & Troubleshooting

Updating to cross-seed v6

If you are updating from version 5.x to version 6.x, you can visit the v6 migration guide for the changes and updates.

General Suggestions

  • The log files in cross-seed's logs folder—specifically verbose.*.log—are your friend. If you experience undesired results from cross-seed, look to these files first for indicators of why cross-seed performed the way it did.
  • In the past, cross-seed has been less opinionated about what settings work well. After a few years of experimentation, we have settled on a high-performing set of default settings that should work well for users and trackers alike. If your configuration predates v6, consider adjusting your settings to match the defaults.

Does cross-seed support music torrents?

While cross-seed may incidentally find some music matches, it is not optimized for music at all. You will find better results with tools designed for music cross-seeding like fertilizer.

tip

Look in your music trackers' wikis and forums for more resources on cross-seeding music.

What can I do about error parsing torrent at http://…?

This means that the Prowlarr/Jackett download link didn't resolve to a torrent file. You may have been rate-limited, so you might want to try again later. Otherwise, just ignore it. There's nothing cross-seed will be able to do to fix it.

Does cross-seed work on public trackers?

Don't add public trackers to your cross-seed config (i.e. as a torznab URL).

Public torrents on multiple trackers usually all have the same infoHash, which is different from private torrents. Because of this, cross-seed does not consider these torrents matches because it looks like you already have them.

In theory, we could add the announce urls to the torrent already in your client, but public torrents make heavy use of DHT and PEX, which are decentralized mechanisms for finding peers to seed to. Therefore, the role of a tracker in a public torrent is somewhat redundant and new trackers usually won't give you new peers.

However, it's fine to download something from a public tracker and then cross-seed it to private trackers, which cross-seed supports automatically.

What's the best way to add new trackers?

Just add the torznab url to your config. cross-seed will automatically queue searches for your catalog on just the one indexer.

What should I do after updating my config?

Just restart cross-seed.

If you've changed your eligibility filters or your matchMode (e.g. enabling partial matches), cross-seed will automatically re-evaluate previous cached rejections.

caution

It will never be necessary to delete your database or torrent_cache folder to perform a "fresh search". Doing so only puts undue stress on indexers.

Can I use special characters in my URLs?

To use special characters (!@#$%^&*) in your URLs for user/passwords, you will have to use URL encoding for ONLY the portion of the URL containing the special characters.

For instance, if your user or password contains a special character #, you will need to go to URLEncoder.org and encode THIS PORTION OF YOUR URL ONLY!

Replace the original user or password with the encoded one in your config file.

My cross-seeds are paused at 100% after injection

This is by design and due to the way data-based searches function. This is done to prevent automatically downloading missing files or files that failed to recheck. Until there is a way to guarantee you won't end up downloading extra (not cross-seeding) this is the best solution.

Alternatively, if you wish for torrents to not inject in a paused state, you can enable skipRecheck in the config file, and this will instead Error on missing/incomplete files.

tip

Consider using infoHash rather than path in calls to /api/webhook to prevent mismatches if you are racing.

cross-seed does not support magnet links. If your indexer supports torrent files you will need to switch your settings.

rtorrent injected torrents don't check (or start at all) until force rechecked

Remove any stop_untied= schedules from your .rtorrent.rc.

Commonly: schedule2 = untied_directory, 5, 5, (cat,"stop_untied=",(cfg.watch),"*.torrent")

SyntaxError: Unexpected identifier when I try and start cross-seed

cross-seed configuration files are formatted with commas at the end of each identifier (option), if you are seeing this error it is most likely that you are missing a comma at the end of the setting BEFORE the identifier specified in the error.

Alternatively, you could also be missing quotes around the value you provided. Check the syntax before and around the config setting given in the error.

RangeError: WebAssembly.instantiate(): Out of memory error when starting

If you receive this error when trying to start cross-seed, usually presenting in shared seedbox environments, it is likely caused by a limitation in the virtual memory able to be allocated to your instance of cross-seed.

To fix this error, it is necessary to use at least Node v20.15 and set the NODE_OPTIONS environment variable to include the --disable-wasm-trap-handler. flag.

To ensure a successful startup of cross-seed, you can simply execute cross-seed with the following command.

NODE_OPTIONS=--disable-wasm-trap-handler cross-seed daemon

Failed to inject, saving instead.

The best way to start troubleshooting this is to check the logs/verbose.*.log and find this specific event.

You will be able to see the circumstances around the failure and start investigating why this occurred.

My data-based search is searching torrent files!

Torrent files in torrentDir take precedence over data files with the same name and are de-duplicated.

If possible, cross-seed will always attempt to create links for data and torrents being injected into a client, so the end result will generally be the same.

If you wish to search only for data files, you can set torrentDir to null, but we generally don't recommend it as torrent-based matching is more efficient than data-based matching. RSS/announce is also only supported with torrent-based matching.

Error: ENOENT: no such file or directory

This is usually caused by broken symlinks in, or files being moved or deleted from, your dataDirs during a data-based search. Check the /logs/verbose.*.log files for the file causing this.

caution

If you do not link files within your dataDirs or have them outside of the maxDataDepth visibility, this is preventable.

My torrents are injected (qBittorrent) but show missing files error!

If you see injected torrents show up with a missing files error, it is likely because you do not have a save path set for the original torrent's category that cross-seed was cross-seeding from. You should also see a warning in the logs when the torrents are injected telling you there is no save path set.

tip

Set a save path for the files in that category to fix this.

I am getting 0 torrents found with qBittorrent and I set my torrentDir

If you are using qBittorrent 4.6.x, 5.x, or later, and have the option to use SQLite database in the Advanced menu in preferences, you will not be able to do torrent based searches. To be compatible with cross-seed you will need to switch this to fastresume mode and restart qBittorrent. This will store actual torrent files in your BT_Backup folder. cross-seed depends on, and indexes, the torrent files for searching.

We have no current ETA on integration with qBittorrent's SQLite database storage mode.

I'm getting errors in cross-seed on hostingby.design seedbox

  1. Get your shared instance IP address (`cat .install/subnet.lock)
  2. Torznab URLs should be: http://ip:port/prowlarr/[id]/api?apikey=[apikey]
  3. Your torrent client should be on the same subnet (if installed after dec. 2023). If not, update the “bind ip” address in web ui settings to your ip from step 1 and restart the torrent client
  4. The torrent client address URL in cross-seed config should be http://user:pass@ip:port (note: no /qbittorrent or /deluge etc at the end)
caution

The subnet/shared instances are reverse proxies so no https

tip

Although we are providing the information given from hostingby.design, we are not able to support this directly. This is just what was passed to us. Contact them for details and further instructions if you have any issues

I can't reach my Prowlarr/Jackett/cross-seed/torrent client (Using Docker/VPN)

If you are using Docker, you cannot use localhost as an address to communicate across containers. Consider using your host's local IP address (usually a 192 or 10 address) or the container name (if using a "Custom Docker Network").

If your setup is running with a VPN, you will need to either

  1. Set up split tunneling
  2. Try to use the Docker network addresses as your instance hostnames
  3. Address the routing of local/internal traffic in your VPN configuration

Generally, you won't be able to access local instances from services utilizing a VPN since localhost/LAN is not accessible from the VPN network by default.

info

There is no need to put cross-seed behind a VPN. All of its requests are made to your torrent client or Jackett/Prowlarr. The only exception is when announcements are made via the /announce API endpoint and are snatched during matching or for injection.

danger

Even with API authentication, we still recommend that you do not expose its port to untrusted networks (such as the Internet).

Searching media libraries vs. torrent data (data-based searching)

You can search both your media libraries (Arr/Plex) and actual torrent data (downloaded files). If you are using the media libraries with renamed files, you will need to use matchMode: "risky" in your configuration file to allow cross-seed some leeway in its matching process. "risky" matchMode is not recommended to be used without skipRecheck being set to false, as it could result in more false positives than "safe".

caution

Due to the way data-based searching works, risky matching only matches renamed files if they are a single-file searches. As TV libraries usually include renamed files, data-based matching will not be able to pick up matches on multi-file torrents (such as full-season packs matched to your season folders).

Why do I see it has a different file tree in my logs?

This is a result of the matching algorithm used by cross-seed, and is most commonly associated with only a few scenarios. These include the presence of additional .nfo/.srt files in a torrent, differences in the organization of files (one torrent having a folder while the potential match does not, or vice versa), and discrepancies in the filenames within the torrent. Setting up Partial Matching will ignore these extraneous small files during matching, and improve your match rate at the cost of redownloading some of these small files.

tip

You can use the cross-seed diff command to compare two torrent files and see exactly how they differ.

How can I use autobrr with cross-seed?

If you are using autobrr to cross-seed, you can use the /api/announce endpoint, rather than /api/webhook, to match against what cross-seed already knows about your available media (instead of searching your indexers every time).

tip

If you want to filter announces even further, consider setting up more specific filters or using omegabrr (which filters based on monitored items in Arrs) to minimize needless calls to cross-seed.

info

For more help setting this up, you can head over to the autobrr documentation for 3rd-party-tools.

My tracker is mad at me for snatching too many .torrent files!

In order to prevent false positives, cross-seed snatches some torrent files that may not ultimately match your owned torrents. It preserves every torrent file that it snatches.

We have spoken to admins at several trackers and have settled on a set of default settings that these trackers prefer. If your tracker has reached out to you about your usage of cross-seed, consider reverting to the default settings of excludeOlder, excludeRecentSearch, searchCadence, and searchLimit.

caution

Your tracker may have opinions on cross-seed's behavior regarding snatches, and it is important to respect these or risk your account being disabled.

cross-seed reduces unnecessary snatches of .torrent files as much as possible, but because it needs to compare the files inside the torrent as well as their sizes, it is sometimes unavoidable. To improve matching efficiency, consider setting up ID-based searching, which searches based on IMDb IDs and often results in less strain on trackers, more specific search results, and less unnecessary snatches.

cross-seed is not aware of what matches will happen ahead of time, each is performed with zero knowledge of the previous or the following. As such it possible to have situations where a partial match when complete would become a perfect match for another otherwise partial match. This is usually neglibile since the missing data is small, but in cases where it is significant such as with seasonFromEpisodes, you can use the inject feature.

If you have not recently deleted files in your outputDir, then these torrents will still have their .torrent file present. If so, simply pick one torrent to complete the download on and that's it! cross-seed uses all possibles matches to source files with the inject job or when using cross-seed inject. It will automatically detect the newly downloaded files, link them to the other torrents, and trigger a recheck for those torrents.

For the rare case that the .torrent files are not present in outputDir. First, choose which tracker you'd like to complete the download on and start the torrent. Then copy (or export) the .torrent files from the other related partial matches to a safe place. Once the download is complete, follow the steps here to re-inject the copied and renamed .torrent files. cross-seed will automatically use the newly completed torrent over the previous (or ensemble) that caused the partial match.

danger

WARNING Manual injections such as what is performed here requires the renaming of .torrent files for proper linking.

How can I force inject a cross seed if its source is incomplete?

cross-seed will not inject matches if the source is incomplete in most scenarios. The only time cross-seed will, is from the cross-seed inject command or from the inject job. If the age of the saved .torrent file (determined my last modified time) is older than a day, cross-seed will inject and link files even from an incomplete source if linkDir and partial is enabled. These injections will always be treated as partial matches which are paused and rechecked.

Once the torrent has finished rechecking, it's progress could be anywhere from 0% to 100%. You will then have to choose between resuming the torrent or removing it from client with the corresponding .torrent file in outputDir. Of course this is no longer "cross seeding", but it does allows the possibility of reviving the stalled torrent used as the source. In order to do this, you may need to follow the manual steps outlined in the faq entry above on the stalled torrent.

caution

This is not really "cross seeding" anymore and likely will incur significant download for the matched torrent. This should be rarely needed as cross-seed can match from multiple sources. cross-seed is simply offering you the ability to revive the stalled torrents inside your client.
