Every time I try to join an official hosted/dedicated server, I get the error "You can't join this party right now. Please try again later." PC hosted servers work fine, but none of the servers with a PC Icon work.
Things I've tried:
-Cleaned PC/Registry
-Changed base port 2-3 times
-Changed IP address to static
-Forwarded all ports for the base Halo 2 game and Cartographer
-Disabled Firewall
-Disabled Anti Virus
-Updated Cartographer
-Restarted router/PC.
I really wanna be playing good old Halo 2 but nothing seems to work and I feel I'm doing everything I'm supposed to. ANY help would be appreciated ty <3
