I don't stop my computer when i'm home and playing/supporting,but when i work or i sleep my PC is out , and i restart it when needed after a update,just like this morning.
clear cache and cookies then restart pc?I tried already.
The funny into this it's if i stay active on the page,supporting friends,training players or another thing,i don't loose connection,but if i don't do anything (like when it's time for assos games or just no games to support for a long time) then connection close after 10 or 15min.

Tha'ts why i asked if the connection close automatically when we are not active for some time.
