Attached is the log generated with grpc v1.11.1 . My test application looks to behave the same way.
Everything looks fine from a grpc API perspective after the wifi connection is being turned off around 9h34m35s. Wifi connection is turned on around 9h37m00s and test application processes messages from the backend around 9h37m29s.
