I am getting the error where it says "Unable to connect to server. Your firewall may be blocking etc..." anyone know a fix for this? I have done everything the older posts say like configuring your firewall to allow league and resetting your router but neither worked. Also anyone else getting this problem?

Riot pls help!

This just started to happen to me. First at school on my laptop and now three days later on my home desktop. Now, I know its not my firewall because my desktop allows LoL completely and it hasn't had this problem at all in the past. Your not alone friend. Riot plz help.
