I have a grpc server in in javascript and client in java running android api level 25. I am trying to use bidi stream to communicate using between the client and the server using keepalive settings. When the android client initiate a request I send a metadata before any streaming calls. But after few seconds ( 5 to 10 ) it receives ‘System.err: io.grpc.StatusRuntimeException: UNAVAILABLE: Keepalive failed. The connection is likely gone’ even though the server is up and running.
