SMB subtitle issue

[daethlor 1]

I have an issue with ASS styled subtitles playing from an SMB share.  To be clear it's only via SMB.  When a local path everything works just fine.  If I turn off the subtitles for the video file, it plays without issue.  This is only affecting the 4.9.1.80 release on docker/unraid.  The previous 4.8.11.0 had no issues at all.

It doesn't matter if I use my browser or android app to play.

Sorry, not just smb, but this file's ass is the only issue that broke with the update.

Here is the server logs.  After 6-7 hours and a few restarts it seems to have resolved itself.  Nothing changed on the SMB share or the copy of the file locally.  Not sure what happened.

It never retried after that failure.  What other logs do you need to see what is happening with that subtitle manager?

OK I see the issue. We will get the fix into a 4.9.x update. Thanks.
