Today I started a game on rift as usual, but after champion selection when the game loads, there was a black screen, and eventually an error box that said "Unable to connect to server", and then some other text about how it may be a firewall issue. I don't think that's it, as I've allowed all instances of League in my normal firewall (Although there doesn't seem to be anything about League in the Windows Firewall), and I've even tried disabling the firewalls.
I personally have been playing League at my current location for 3 months now, and there haven't been any problems. I cannot personally open ports in my server (I have considered opening ports 5000-5500 but I cannot actually do it myself), and I don't see how that would be the problem considering how long League has been working before this.
This topic seemed to be posted before(?) but had very little reponse, I am also reposting in case someone else is having the same problem.
Thank you for your time, and I apologize to whatever players I abandoned in the game that was unable to enter.
