My Plex server don’t has a fixed IP address because my internet provider disconnects every 24 hrs so that I get a new IP (that’s the common approach here in Germany for private accounts).
If I use web log in in my local network it stops working from the outside. If I use web login from outside it works as long as my provider gives a new IP.
I also tried the username/password+2FA connection together with my external fixed host name (xxx.myds.me domain + custom port) but this also works only as long as IP changes again. Maybe because 2FA is no longer valid after change?
This never was a problem with Plexamp. It always got a connection somehow.
