Jumain360 0 Posted September 19, 2020 Hi. I've been trying to join a game through System LiNK on my Xbox 360 but I'm getting an error message. Example: when I try to join a game in Halo Reach, it gives me something like this: "The group you're trying to join may have an incompatible network configuration. Your NAT OPEN configuration is usually supported". When I try to do so in COD Black Ops II, I can see the groups and the games, but I can't join. I've already tried changing the ports in Nova configuration but it still doesn't work. I'm getting this issue since I called my ISP to open some ports for me, but I don't know how to fix it, I mean, I used to switch or change the ports to solve the issue but it doesn't seem to work anymore. What should I do? Quote Share this post Link to post Share on other sites
