Hi Team,

We want to upgrade the java and python grpc lib of our system. They both run in the container. After the upgrade, we find the java container doesn't send out the grpc message. I used tcpdump to verify.

If the java code run in the host network(not run in the container), the communication between the java code and python container are good. 

We'd be appreciated if you could reply.

Details:

-> pre upgrade:

java lib:

io.grpc: 1.30.2

com.google.protobuf: 3.17.3

python lib:

grpcio==1.34.1
grpcio-tools==1.34.1

protobuf==3.14.0

Can you enable debug logging in the gRPC Java application? It would be of interest any logs from the name resolution, such as the logs here about addresses resolved or conversely from the onError callback.
