Myflightaware piaware connection refused of and on chrome


Hi this is my first post I will make it short I hope. Ok if I leave my piaware running on my pc and wake up the next morning it looks like the screen or program freezes theirs so many air craft on the screen and nothing moves I reboot the piaware and its ok but sometimes I get connection refused when login into my locale I have a pro stick and a pi 2 unit I feel that google chrome is the problem but not sure. I ran the piaware for almost 400 days stratight no problems I did do a piaware program upgrade thru my flightaware its the connection refused that’s got me jammed up could the pi be going to sleep or time out off and on thanks
