I use Syncthing to sync files from a seedbox (send only) to a local server running Unraid (receive only) for Plex. I’m running into an issue where some files are being skipped even though the folder and other files (like info or subtitles) will send. I can’t find a pattern to what is not being sent between the two. For example, an episode downloaded by Sonarr last night only skipped the mkv in the sync, but an episode of a different series downloaded earlier that night did properly sync. Has anyone else encountered this issue or any advice where to look? The only ignore rule set up is to skip .rar files and these files are .mkv.
It’s difficult to say what is going on exactly, but what is certain is that Syncthing itself doesn’t care what the file extension is. Usually these kind of problems are caused by things like permissions, etc., where Syncthing has no access to the files in question.
You could try to enable fs (and maybe also walkfs?) logging in Actions → Logs → Debugging, then rescan the folder and see if there is anything recorded in the log that could be related to the files that cannot be detected.
Thanks for the advice. I enabled fs and walkfs on both sides and rescanned. It looks like certain folders are being skipped over. I’ve attached screenshots below of the logs. I tested this with the movie Ted, which is not being synced properly from the seedbox to unraid. One thing that’s strange is I tested this recently with a new movie to see if this is a new permissions issue. The new movie synced and imported without problems. It looks like for the Remote Device on the seedbox side it is showing syncing at 0%, but the Remote Device on the unraid side is showing Up To Date (but with local additions on the shared folder).

I think I figured this out. For anyone who comes across this in the future it was the ignore rules I had set up. They should have only been ignoring .rar files from transfer, but I think it was ignoring any file with a .r in the name, which caused it to skip files.
Using this ignore rule seems to be working properly: (?i)*.r{[0-9][0-9],ar}
