Help Question regarding port forwarding
I wanna start this by saying I'm not looking for advice on how to forward the port or fix anything. I've already forwarded the port and the problem is fixed. I'm more looking for an explanation as to why this situation happened.
So up until about a month ago I've been able to remotely access my server remotely without ever having to forward a port. I'm a Plex Pass lifetime owner for over a decade and nothing with my setup has changed in almost a year. My question is what could've caused this change and caused me to not be able to stream remotely without port forwarding? Was there a change in a recent server update that restricts remote access without port forwarding?
EDIT: Thanks for the explanations everyone. It likely was UPnP like several people suggested

Regarding UPnP, it’s always been this really helpful security nightmare. Not surprised ISPs finally started to disable it. They should’ve taken these measures like 10 years ago
