Can't connect to any gaming servers

I am using a desktop with a wired connection. I can use Skype, surf the web. I can login to Steam on the browser.

I can't connect to League of Legends (logging in gives me a "Can't connect to maestro server" error). I can't connect to Steam (which gives me a "Can't connect to servers. Check your connection." error). I have flushed my DNS, checked proxy settings, checked internet settings (IPv4 DNS config), renewed IP, even checked hosts file.

On the other hand I can somehow play Hearthstone. On a laptop with a wireless connection I can login to League and Steam.

Any ideas?


According to the League of Legends Forums (here) you can try this:

Some sort of Maestro Error

  1. Restart your computer
  2. Temporarily Disable/Make exceptions in your Anti-virus/Anti-spyware software
  3. Temporarily Disable/Make exceptions in your Firewall
  4. Disable process protection software.
  5. Make sure you're running software in Administrative Mode/With admin privileges
  6. In Windows Vista/Windows 7, double check your Account Controls
  7. Reset your Internet Explorer Settings and make sure you have not disabled scripting options

One person solved it by going to

C:\Riot Games\League of Legends\RADS\projects\lol_air_client\releases\0.0.0.237\deploy

and setting LolClient.exe to run as admin.

One person updated Windows by running Windows Update and the problem was solved.

It's quite a common error and many people have odd ways of solving it. But since LoL and Steam don't connect I assume it's strictly connection or permissions.

EDIT: Here's a video that explains how to fix the problem. (He explains the Maestro Error at 2 min 24 sec. It has to do with Anti-Virus ;) )

I've had this happen to me and it was the Anti-Virus I was running (Kaspersky btw). I tried white-listing it on the firewall, Virus list EVERYTHING and it still didn't work. The only way I managed it to work was to play with the Anti-Virus turned off. (But this was my personal case).

END EDIT

If you can solve it for LoL you will most likely solve it for Steam.

I wish you good luck! and I hope that I gave you some good things to try and fix the problem since we never know for sure what the solution is.
