Comment 9 for bug 1518300

The behaviour that i've noticed is that the messages are not missed, but received after passed 2 or 3 minutes after the app comes to foreground again.

I tested the state of the QTcpSocket when not got the inmediate update and was QAbstractSocket::ConnectedState. Besides, the socket was marked as valid, open, readable and writable.

The socket is used to send a request to the telegram servers getting the differences (the updates) and QTcpSocket logs that the request is sent (N bytes written in the socket with no error), but no response is received.. until passed those 2 or three minutes
