So for like 2 months I've been trying to figure out how to host a game and have my brother join. I really wanna play coop campaign with him and i found this tool on this page: https://halo2.online/threads/coop-mode-update.468/ So now I'm trying to host a server but every time I do i get this error: https://imgur.com/a/e5D4L After lots of google searching I came across this post: https://halo2.online/threads/tutorial-project-cartographer-on-2-pcs-no-vpn.950/ I followed L0RCH's guide but it still doesn't work and i get the same error. So if anyone can tell me how to fix it that would be very awesome
