@magge Ive tried disabling firewall and nothing changed. My router has 3 networks. 5 ghz and 2.5ghz. (all networks work and ive played and connected to FAF with all 3)

Ive noticed that when I get this error I can usually switch networks, try again, and about 80% of the time I can log in and play a game.

Ive just now tried to log in. Usual error. Used VPN and tried again and was able to log in. I disconnected from VPN and tried logging in 3 times and each time it allowed me to connect.
