I installed league of legends on ubuntu 14.04 with play on linux. Everything was OK I played for a month but when once i updated my ubuntu then when i reinstalled LoL and tried to log in it said "Did not revieve response from a server".
I saw a solution when this problem appears on windows. They open internet explorer and it solves the problem. I also installed the IE with play on linux but it did not help.
Sorry for my english and thanks for answers!
