Quick update...
I tried deleting my profile in the User directory again and was able to connect to the server, left and then tried to rejoin and got the same problem. Repeated this whole process again but this time it didn't work, tried 3 or 4 times with no success so its pretty intermittent.
One thing I noticed, yesterday when I was able to join my rank had gone from 52 down to 46, today when I joined it had gone down to rank 0 (game is trolling me

) but this might be linked to me keep deleting my profile. I don't think its a problem with your server in the traditional sense but completely stumped by it tbh, strange that repeating the same procedure may or may not work and usually doesn't. Perhaps it only works on the profile delete the 1st time after the system is started and something gets cached.
Given two other ppl have reported similar problems, I wonder if a Window update or McAfee update has introduced some issue. Everything was fine up until either Thursday or Friday night and then failure since then, I haven't changed anything on the computer in that time and the only other game I've played in that time is Hitman Go.
Sorry for rambling on but wanted to show I have tried to resolve things on my own and wasn't just throwing the problem at you. I don't really expect theres much you guys can do and tbh wouldn't expect you to waste your time, I'm sure you have enough to do. But the info might be useful to anyone else getting the same problems.
