Problem after move plexserver on another linux server

Server Version#: Latest
Player Version#: Web

Hello,

I migrated my Plex server to another Linux machine behind a pfSense firewall with a different public IP address.

Since then, I haven’t been able to regain external access.

Here’s what I have in the logs:

Thank you for any help.

Can we start with an actual copy of your server logs instead of the excerpt?

Should be port 32400, did you put an entry in custom server access?

Those log entries are referring to a (old) xTeVe/Threadfin virtual HDHomeRun tuner (I’d guess). Port 34400 is their default and ‘discover.json’ is the endpoint for finding tuner information.

In the context of what’s been provided, it’s just noise (as are the DVR error logs around them).
