I have now done everything in my power to fix this without having to toss out more money on a router because bungie can’t fix their errors. i have tried port forwarding, i have tried unbinding port 3074 as one post said. i have enabled upnp. these are all the steps i have found after hours of research of this error. im running a thomson tg789vn and i know that’s the source of this issue, but i really shouldn’t have to pay up another 200-300$ to buy a new one. if anyone has any information about another fix other than these ones, please let me know. i have been struggling with this for way too long now.
Unfortunately, there is nothing that can be done other than swap out the modem Guardian. This has been a known issue since the launch of D2 and it has to do with ports being locked on the router specifically set aside for VOIP. This is a problem with the modem firmware not with the game.
