Cannot connect to multiplayer games

If I chose find game I get a 'no game found' notification and if I chose a server I get a 'lost connection' notification generally after a few seconds of a 'preparing server' notification, the same occurs if I am in a party.

(I sent a message to support with logs about a month ago with no response so far)

Have you done any troubleshooting?

im getting the same error nowhere online can i see any troubleshooting for it

I've done the standard troubleshooting steps:
1-clean reinstall on a different drive
2-deactivating firewall to see if that's the problem
3-some fiddling with network/VPN
I'm pretty sure I tried some other stuff but its been a bit so I'll leave it at what I'm sure I did.

I also replaced my GPU, RAM and added an SSD recently so I've had this problem on 2 different hardware setups
