If you want to be a pompous PITA, Ill forgo providing any assistance and forwarding the results to the relevant staff. Instead of being a Karen take the help when offered.
The only thing exposed in logs is going to be your email and your public IP address. Tokens or anything account private will censored. The logs are designed for public posting and troubleshooting.
I would start with a couple of points. I would set your docker to host mode, and turn off/disable the other network cards in the container.
Then I would look at your network settings, as I am seeing Allowed Network (Subnet) in your logs suggesting you have non-default network configurations.
Thank you, I’ll try those. Have you ever seen an authorized device show up like the attached picture? That is what I get when I use the UserCredentialReset utility. The utility runs fine.
It was Tailscale. One of my servers containers was trying to use Tailscale as it’s NIC. I stopped Tailscale, started Plex, authorized perfectly. I set to advertise my IP in docker compose hoping it will avoid this in the future (it was trying to use 100.100.100.100).
This problem was driving me nuts. Hopefully it helps someone else in the future.
