I reinstalled Plex Server on over a fresh Win 11 install on an Intel NUC that I had installed Plex on before. Unfortunately, I’m on T-Mobile, so I’m stuck in Double-NAT hell with a POS gateway and forced to use the Relay Connection. Up until the reinstall, it was working fine and the only person who uses it is my GF to stream to her phone.

After the re-install it is so slow that it takes forever to load and will not play back any media. I’ve done all kinds of troubleshooting, including doing another clean Windows and Plex installs. I haven’t found an obvious fix in various forums.

Can someone who knows more than me look at the logs and let me know if there is something I am missing.

Or, has anyone figured out how to get direct remote to work with T-Mobile in a straightforward manner?

TIA
