Constant 'lost connection to game server' + In game models and UI being invisible

For some reason after starting Overwatch, my game will freeze and the ‘lost connection to game server’ screen will appear. If I join a game in this time, all the characters are invisible including my UI (crosshair, first person player model). Its not my connection since every other game runs fine with no connection issues, all my drivers and software are updated. I have uninstalled and reinstalled Overwatch, reset my settings and deleted the cache file yet it still does this. This all started after the recent update.
