Good morning everyone, I have had this problem for more than a month, but I didn't post before because I hoped it would be resolved with a patch. Since it didn't, I'll ask you for help.
I've already read other threads and i tried some of the solutions but they don't work.
When I start League Of Legends, in the log-in screen the message "There was a problem connecting with Maestro" appears and i have to close the game. If i reboot the pc it "resolves", but I don't like to reboot my computer everytime because it's quite annoying.
Furthermore, when I downloaded the last patch I had to repair my client to make it work (because even rebooting it didn't start): it now works but it's the same as before.
I hope you will be able to help me, thanks.

bump.

Hi there!

Based on the information you provided, this seems like a problem with your connection to our servers. Most often, these connection issues are caused by overzealous firewalls or anti-virus programs. Many firewalls are installed automatically with Windows, so you may have as many as 3 and not even know it.

We have a detailed guide to configuring your Firewalls to work properly with League of Legends. However, even when properly configured, the disabled modes or exceptions lists often do not function properly for 3rd party firewalls. In these cases it may be necessary to uninstall them. If you'd still like to give configuration a shot, you can view the article here:

However should these solutions now work I do encourage you to log a support ticket here.

These type of issues can potentially require some back and forth, to speed up the process please also provide us with:

Information about your network configuration: http://support.leagueoflegends.com/e...etworkinfo-log

A Netalyzr: Just go to http://netalyzr.icsi.berkeley.edu/ and run the test. Once the test is complete, copy the full url and paste it into the support ticket.

Thanks!

If anyone is still having trouble with this, I managed to sort it today:

- Open you firewall settings
- Ensure that all LoL-related programs have full internet access, and are unblocked.

Mine started working again the instant I unblocked AdobeAir Debug Launcher. Hope this helps.

restarting computer worked for me

The maestro error happen to me when i update the new League patch and to make league of legends work again i had to restart my comp i got tired of it and some how i found this video that fixed my problem
