Cannot connect to 4 or more people...
 

No matter who, what server I'm on, I can't party or pvp with a party of 4 or more people.

It ends up lagging, and/or doing the cannot connect firewall thing.

I don't think it's a connection problem but... Mabye?

(2,3 people results in no lag)

Any fixes?...

Have you tried port forwarding and disabling firewall?

That connect firewall thing happens to me too, but it's usually random. It stops for me after a few tries.
