unexpected disconnection

With new Kepeers league there is so many unexpected disconnection. Terrible game, imposible to play with. I tried with many server: Texas, Washintong, Canada, Australia, etc with same result.
Check server with WinMTR. Result: All OK.
Disconnection only occur with POE. Normal connection with other games.
It was normal before Keppers League.
Reported many time with /bug in chat, but problem is not solved.
