I've been seeing this lobby error (2002) also with Primal since last night. I was hoping it would be resolved this morning.

Restarting my PC and unplugging my router for a spell didn't help. No amount of resetting my connection or flushing dns has helped.
Disabling firewall didn't help.

I have been able to connect to other Datacenters, but I don't play on those.

Server status for my server says it's up and everything should be ok.

Is it Primal or is it just a handful of users?
