There is nothing that can be done on the side of plex.tv
Authentication servers are all up and working normally https://status.plex.tv/
Did you follow the link I set above?
If your ISP has integrated the McAfee security software in their systems, you need to disable it or wait until they have updated their block lists. They have blocked the main plex domain name for all your servers plex.direct from working.
Apart from that:
- check that your ISP has not put you behind a CG-NAT https://en.wikipedia.org/wiki/Carrier-grade_NAT
More and more ISPs do, due to the shortage of IPv4 addresses – even existing customers. - after a major Windows Update, verify that the network connection is not back to ‘public’ classification
- after a router firmware update or the exchange of the router, verify that the network connection in Windows is not back to ‘public’ classification
- If you have been using the automatic configuration until now, switch to the manual port forwarding. Don’t forget to tick the checkbox and don’t confuse external and internal port numbers: https://support.plex.tv/articles/200931138-troubleshooting-remote-access/
- look up the external port number under Settings - Server - Remote Access
Use canyouseeme.org to test its availability (must be done from inside the same local network as the Plex server).
The behaviour to show the availability at first in green is normal. The connection check is only performed after you enter this page. So if the check is turning out negative, the status appears to switch to red after a few seconds. When in fact it has been red from the beginning.
