Match and Fix Match Stopped Working. ERROR (networking:196)

Server Version#: 1.22.0.4163-d8c4875dd
Player Version#: 4.51.3

Match and Fix Match stopped working with version 1.21.4.4079-1b7748a7b (or possibly 1.21.3.4046-3c1c83ba4). I am seeing network errors in logs… unable to open URLs to theTVdb, to servers, etc. I have attached the log files. This instance of PMS is installed on a windows 10 machine.Plex Media Server Logs_2021-03-13_09-29-03.zip (2.9 MB)

That’s a lot of errors for those agent plugins – not just to those sources but even server internally… did you change anything about this Win10 machine that could interfere / block Plex’ internal communication?

There was an issue with VPN provider around the same time caused by an update to the VPN client. Ended up switching protocol to correct that issue. VPN is not connected, and I use it sparingly. Also installed docker desktop two weeks ago. Other then that, just updates to PMS.

I solved this problem. I shutdown the docker desktop and disabled the WSL2 virtual ethernet switch that was installed with docker desktop for managing traffic between docker containers and windows. Once I disabled the switch, communication with plex agents started working again.

My recommendation to the Plex development team, is to reproduce this problem by installing plex on a windows 10 machine, followed by windows 10 docker desktop install. As part of completing the install, you will be warned that docker desktop needs WSL2 backend to function properly, and you will be provided with a link to install and instructions for setup. Once complete you will have a WSL vEthernet adapter installed and configured. I anticipate that it is this switch that is somehow blocking or interfering with the subnet connections that are configured for Plex. Just a hunch. For now, I am fine with closing this issue and I hope it helps others that might be experiencing match agent connection issues where docker desktop is part of the server setup on a windows 10 machine.
