Access to plex server suddenly stopped working

Plex Media Server Remote Access
1

Server Version#: plexinc/pms-docker:latest
Player Version#: Any

So first I’ll try to explain my server architecture so It’s clear, I have a dedicated server in OVH which is currently running a Proxmox hypervisor (This has an external IP address), I have a single VM on it running Debian on it.
The Proxmox has iptables pre-routing rules to route ALL the plex ports to that debian VM.
That debian VM contains my Plex container, attached it’s docker-compose at the end of the post.

Now to the actual problem, I don’t have access to my movie library but I do have general access to my server when accessing with the Proxmox external IP and when accessing through the local plex IP through the debian machine web-ui.
When I do so I don’t have access to any movie or to the server settings.
When accessing through plex.tv I get the error message “Can’t connect securely to server” which leads me to believe there was a certificate error.

I tried to follow multiple guides, notable this one:
Why am I locked out of Server Settings and how do I get in?
But nothing allowed me to get access to my server settings, not locally and not remotely.

I’ll attach the logs in hopes that someone can help me pinpoint the problem because I’m lost.

I think my Plex certificate has expired which is what leads to the errors in my logs and in Plex failing to connect securely to my server.
How can you generate a new certificate?

Your hosting provider is Hetzner, which has been blocked from plex. See the other threads about why/people complaining
