Playback stops randomly

I’ve used plex for about a year now without issues. As of this week I started hitting this across multiple clients and I have no idea why. Logs just show things like:

Jul 21, 2020 09:33:16.610 [0x7fbf05fa1700] DEBUG - Failed to stream media, client probably disconnected after 465338368 bytes: 110 - Connection timed out

Also lots of this:

I don’t know what to do with this or if it is relevant.

I tried playing the same video back just over SMB using VLC. It buffered a few times but worked. Maybe the buffering is when Plex is just stopping? Either way it worked though.
