We switched to a different tool that’s developed by the same company I work for, and there has been nonstop complaining about it ever since. Jira might not be the best tool, but it’s better than the alternatives by miles.
Also technical shit posting on Confluence is just the best. (I don’t like Atlassian, I just want to go back to Jira)
Do you think you could post a picture of the exact error message? Also you could check the Plex logs through the web app and you should see the exact error and what component caused it. If I had to take a guess, I’d say your uncompressed movie has something that’s causing the server to transcode (TrueHD audio or a forced HDMV subtitle stream) and the transcoding process is failing.
