So idk if this is on your end or mine (probably mine) but i was just playing on the server and i crashed due to discord deciding to launch funny, but when i tried to connect it kicks me back with a different explanation every time from Banned (no reason given) (not on unban because it was only once and im pretty sure im not, and if so i apologize for whatever you think happened) but it also told me my version of 'pl_beerbowl_rc1' did not match and another stated that the servers Html was not responding, i have no idea... im confused and have no idea where to post this so i threw it on technical support, again im dumb so take this all with a grain of salt, sorry again -Thaz (i know im a canadian who apologizes alot ha ha)
You're not banned as far as I can tell. I would suggest verifying the integrity of the game files in the tf2 properties in steam. If that does not work delete the tf2 folder on your computer and have it redownload it. You can also just try deleting your map folder that should fix the map problem.
Thanks, that helped i also found one of my old third party programs trying to run itself on fragmented files so that might have done it too
