User blog comment:PreyOnYou/Major Glitches in DLC PS3?/@comment-2138887-20100626155752

Okay -- so after digging and digging and digging on the "internets" until my nails were stubs, I found the solution to the issue my friend and I were having with the "ERROR Can't connect. Please check your connections and try again" issue. Our NAT settings didn't match. For whatever reason, it's been fine all these months as we've played Borderlands, etc. and even "regular" RDR multiplayer. Hers was NAT 3, I was NAT 2. NAT 3 is strict and can cause chat and game connection issues

She set hers to NAT 2 and we're fine.

Here are two sites that can help (this is for the PS3, but I'm sure there's similar help out there for the XBox):

Also -- if you can't seem to get the NAT to change, check the firmware on your router. She had that issue, then found she was behind on firmware updates. After she updated the router's firmware, she was able to change it to NAT 2.

All is well now.

I still say it's stinky that Rockstar was so mum through all this -- almost like they were pretending it didn't happen (as my friend said). It's really too bad that companies nowadays feel it's a black mark and insulting to their reputation to say, "Sorry -- we effed up. Here's a consolation prize for all of you." That's what my company's done when something's happened and -- surprise surprise -- we gain more respect and customer retainability that way.
