Last two games I tried to play with my friends I get this error. It tells me to check my firewall to make sure I am not blocking it. This has never happened before.

Happened once for a practice game.

Once for a real game.

Happened to my other friends who I was in a premade with.

Going to send my logs via the mailer...but I figured I'd put it up here now to see who else is getting this.

I can't play any LoL games of any sort at the moment.

Thank you for your time.

EDIT:

Here's how I recreated this...bug?

1. Log in
2. Create Premade with two other friends.
3. Go through character choice and the timer ticks to zero
4. "League of Legends" emblem appears on my screen attempting to connect to server
5. "error" message appears "Unable to connect"

And I already mailed in my logs.

5:55 PM EST, experienced the same problem in a Normal game that I solo queue'd for.

I have the same problem in a normal game.
it never happened before,
and i dont make any modifications to the configuration of my pc.

Sorry for the bad english.

Yeah, wth?

I am getting the same problem right now.

I assume that one of the game servers has been disconnected, but is still being assigned games. Wild guess though.

yeah, just happened to me too... hahaha, 13 minute queue time and the game fails... awesome

At what point did you receive the error? On log in, at champ select, from champ to loading? thanks for posting! If it happens at any time in pvp.net we'll need to see your air logs ( Air logs are found by default at C:\Riot Games\League of Legends\air\logs).
