And here I am with another Helldivers 2 on Linux troubleshooting question...
Recently (as in some about the end of Void Piercer), my game just doesn't allow me to up-link to any other ships anymore. I show up as "offline" to all my friends. I have tried switching the proton launcher in steam from Hotfix to Experimental and back, I have uninstalled and reinstalled the game, have switched my VPN nodes dozens of times, restarted, everything, and nothing seems to allow me to link up to other players anymore. I can drop SOS beacons but no one can join.
Might anyone Helldiving on Linux (Linux Mint specifically) know what might be causing this? >.<

EDIT: yup it was my VPN, thank you all!

You mentioned a VPN; I’ve only been able to connect in multiplayer if I’ve turned off my VPN entirely.

It's likely your VPN and Linux combo. Great for privacy but not so great for online gaming (Linux build doesn't officially exist so your likely using Steam Proton)

Try a p2p VPN server if possible

thank you all. Will muddle with my VPN settings after work and return to the front ✊

When gaming, what's the advantage of p2p VPN servers vs normal ones?

On Nord, I just straight up cannot connect to discord without it on arch. Haven't dug around as to why, but it's working as a bandaid

I was concerned about response times but it seems fine
