Server Version#: 1.20.1.3252 Player Version#: multiple Plex stopped generating thumbnails when media is added sometime ago although it will eventually add them during the maintenance period. Also trying to force generate the thumbnails through the Analyze function will no longer work either

I’m having the same problem - Video Preview thumbnails have stopped being generated for me all together several Plex versions ago. Currently on the latest Version 1.20.5.3600. Anyone else having this problem and know how to correct?

4 months later, still having this issue. I can click analyze on a title to have it generate the thumbnails but they are not generating automatically when a new title is added.

Thank you, I do have everything setup as you mentioned. I have been using Plex for years and this only started happening about 1 year ago maybe a little less. Can you let me know how to do the logs and is it possible to send them to you in a private message?

In the troubleshooting section of your server settings there is a download logs button which will make a zip file of all of them. You can message them to me by clicking on my username/avatar and the message button.

You have a bunch of errors in your server log i have not seen before. Gonna need to ask someone about them.

ahh okay no worries, thank you for looking into it.
