I just got a new router last night and since then whenever i enter a league game the loading screen never appears and there is just a blank screen. i have turned off antivirus firewall, windows firewall and my routers firewalls so i know that is not the problem.
I am able to spectate games without a problem.
also if i end my league once and then re open it i get a message saying my firewall could possibly be the problem (which it isnt). if i hit retry on that message it ends up working and my character starts loading in. the only problem about that is that i get in the game at 2:30.
