IPV6 NOT WORKING

Today I got an upgrade to my internet connection to 1gps through an ONT router. It seems that currently when I’m looking up my external adress it is by default IPV6 and the ONT does not allow switch to ipv4. The plex media server currenly says I can;t connect from outside, tried defining a new port, I’ve checked the box with ipv6 support, same problem:
Not available outside your network
Your server is signed in to Plex, but is not reachable from outside your network. Learn more
DISABLE REMOTE ACCESS
Private 192.168.100.2 : 32400 Public 86.124.191.215

It seems that the server can’t even read my external ipv6 adress, it tries to connect through a ipv4 adress.

Any ideas?

Plex does not currently support remote access over IPv6. It is only supported over IPv4.
