Attempted Solutions:
[Have you looked in to whether this could be related to your Anti-Virus/Firewall? Are the appropriate exceptions in place?]
I’ve gone and checked the firewall, turned off ipv6 in the router settings, changing the DNS, changing who’s hosting, changing graphics settings, turned off raytracing, made sure no vpns were on, restarting the game, reinstalling the game, restarting the pc, updating drivers, amongst a million other things.
