_Rendezvous of RPC that terminated with StatusCode.UNAVAILABLE, Error received from peer

Ok, so after trying many things I couldn’t find the underlying cause other than that the error happens after the connection goes idle after some time.

Doing a retry immediately after is possible so with the help of the grpc library it actually not so difficult to handle the exception (example http://avi.im/grpc-errors/#python)

import grpc
…

          if e.code():  # http://avi.im/grpc-errors/#python
                # e.details()    #            
                status_code = e.code()
                status = str(status_code)
                print("Exception Status Code", status_code)
                return status

then look for the error code in the response
e.g. if status == “StatusCode.UNAVAILABLE”:

and try again whenever necessary
