Hi Gearbox…just looking to add mine and my misses frustration at this also! This is 1 of our favourite games, we have put hundreds of hours into this on the 360 and xbox one. But the last week or so, after a long night in Caustic Caverns, we are no longer able to join games. That is neither of us, even via quick match or checking on the match browser.
Our NATS were originally set to Strict and Moderate after moving to Virgin a month ago. After much playing around I have eventually brought a new router and set my superhub to modem only…consequently opening the NAT on both xboxs. I can join other people in all other games, but not BL2 or TPS.
I appreciate you are trying to can you please try harder keen to get back online! The game just isn’t the same without Co-Op.
Info…we are in the UK on xbox ones, can’t connect during the week or at weekends, with our existing characters or new ones.
