Okay so I was hoping this new patch would secretly fix some of these connection problems.
I'm able to play with a NAT type 1 without experiencing freezing. I do still get the error codes from the first post but It's not always as soon as the match starts. Out of about 5 games, I was able to finish 2 of them, 2 of them lost host in the middle, and one of them had the problem described in the first post. I'll kieep you guys posted if anything changes.
It is a connection issue. Why would I receive this problem with every single game I play, PS3 or Vita?
To jsbotaku, I'm gonna try using NAT 2 again right now. As noted earlier in this thread, that caused me many problems before the patch dropped.
Okay so now I've done a good number of games. The only thing that's changed as that I don't get the freezing screen when playing with NAT type 1. All the other problems still persist, including the instant error codes.
