Server Version#: 1.25.6.5577
Web Player Version#: 4.69.1
Around 2 minutes into the film I was watching, the player stop and you see the buffering ring spinning. There are no network issues. I have downgraded to 1.24.5.5173 which is working absolutely fine.
Because I dont want to dedicate a whole machine to Plex. It doesn’t make sense to dedicate a whole machine just to use Plex when the newer version has introduced an issue that causes playback to stop. Items are streaming fine in version 1.24.5.5173. This is definitely not a VM issue
So you are saying if I ran Fedora 35/CentOS 8 this issue would not be present? Even with the knowledge of a working older version? What I can do is choose the normal kernel instead of the UEK which will pretty much make it CentOS 8.5. I will try that and post findings
Update: So I have tested the change as mentioned previously and the streaming still stopped a few minutes in on MKV files. I even tried switching from a Windows share where my media is to an NFS one and same issue.
I re-imaged the VM and used Fedora 35 (is vetted) which resulted in the same issue.
The conclusion here is there is something wrong with versions past 1.24.5.5173
Don’t worry about running it in a VM or using Oracle Linux. I run my server in a Docker container inside a VM so it matters none for basic media playback.
Re-mux the file in question with MKVToolNix and try again.

Stop playing movies inside the web browser. The web browser is the least compatabile player you could be using.
