could not find a server that was suitable

I keep getting this message and am unable to play online multiplayer. I have posted this before and have tried restarting and disconnecting and uninstalling and jiggling cords while standing on one foot… jk about the last one. I am about fed up here. This is a pretty expensive game to only get a campaign. I need help from 343 and cannot get any acknowledgement for this problem. I am not the only one. Wassup man??? HELP!!!

Quit the game and try it again. Works for me.

Tried this a hundred times, thanks though.

Same problem… Restarting 10 times didn’t change a thing…

I’ve been having this problem since Friday. I can connect my 360, so it’s not my internet connection.

Update. It was my NAT setting.
was moderate, needs to be open.
