This is weird. I did a clean install of PMS just to kind of reset everything. Every thing seems ok, except under remote access. I get a red X on both outgoing and incoming. Clearly I have internet access for the PC, and even Plex does, as I can sign in just fine. What I see:
Private Unknown IP X Public Unknown IP X Internet
This is all the same setup. Same port forwarding etc. Everything is working fine except Remote Access. I tried re-installing again and no help. I've tried turning off the firewall and so on.
