Call of Duty

[TRS-T]

Ever since the connectivity patch, I've experienced the "Stuck on Downloading Game Settings" problem.

At virtually the same time as I started to get that, I now can't connect to certain friends. When I accept their invite, it says "trying to join potential matches" for a while, then it says "Unable to connect to host."

This only happens with certain friends, not all...

Can anyone tell me why this is happeneing...never experienced anything like this before the connectivity patch.

Any help would be appreciated...

PS: COD4 Online is making me ANGRY!

I get that aswell. Some friends it works fine and with others it won't.

You need to open your ports, its a common issue.

what ports do you open and how do you do it?

This problem is due to either you, your friend, or both NAT Types. You need to follow these steps to make it work : 1) Open up required Ports: (TCP: 80, 443, 5223) (UDP: 3478, 3479, 3658) 2) Put your PS3 into a DMZ. 3) Enable UPnP on your router.

Hope this helps

Hope this helps I get the unable to connect to host, and my PS3 is in a DMZ+UPnP is enabled. It just says not applicable on the ps3 when i do connection test. Only sometimes though. Not all the time.
