Could not connect to Lobby Services#667

Yesterday and today I have been getting this error that makes any sort of lobby completely unplayable for me. Any time I try and join or make one it says there was a lobby service error. I have restarted my computer, verified game files, updated my drivers, still nothing. Attempting to make a lobby in Casual or 2v2s will just crash my game entirely, same with joining someone inviting me from steam.

I have no idea why this is happening only now or what is causing it, but I figured I would make a post about it. Being unable to play with friends online sucks. I can still queue, but as someone who likes to compete in online tournaments a lot, this effectively bars me from entry.

I am still having this issue after nearly a week. It is extremely unfortunate and has made me resort to queuing casual at the same time as my friend and hope we end up together. I have tried tons of potential solutions to this and nothing has worked. Changing DNS, restarting my router, nothing has worked. It’s truly upsetting as someone who normally plays this game with friends every other day bare minimum
