"Scan Library Files" on any single library does nothing

[Nabukodonosor 13]

The same thing happens to me. I have several libraries, and one was a folder with some theater shows. I was a mess, never got a chance to sort them. Now, I've put every show in it folder with year etc. And now I want to rescan the thing...I have also added a couple of new shows. Nothing happens. The same thing TheBlueSpirit described. When I go to the web player to play some of the shows it says "No compatible streams are currently available. Please try again later or contact your system administrator for details." Of course. It's not there anymore. I've changed the path to it. But Emby for some reason doesn't want to scan it and change it. It's a bug. I will just have to delete the whole library and do it all over from the scratch.

OK. Here's my library:

https://prnt.sc/6KRwCzaqhXGd

The marked one is the problematic one. In that folder I had some files, all in one main folder called Predstave, with a few subfolders. Now I sorted all out, places all files within their own subfolders with a year in the titles. For example "Predstave/Show 1 (2025)/". Also added couple of news shows. Now I go to 3 dots in my Predstave library, click Scan Library Files, I get that popup saying it started scaning but nothing happens. There's no that green circle with %. I've attached debug log file.

So, this is unsolvable?

Well it looks like its not there or emby does not have permissions to it.

Yeah, the moment I posted the post I found out that for some reason my path was removed from the docker compose file. I added it again and everything worked again. Thanks.

Nice to hear that
