Cannt access server

I was just using Wifi to run Gunz and i could log on to the server fine, but i lag with Wifi. Now that i am using an ethernet cable i cannot login but i can see the servers. It also cant connect to the patch servers but the front page comes up where it listes the updates and dates. Im allowing gunz through firewall. Any ideas whats wrong?

Hey, I also had same problem I fixed by,

, i just permanently disabled windows defender and allowed gunz and launcher in firewall and offed firewall and restarted router and cleaned registry (Using CCleaner).
