Stacktraces and logs

Do you have any relevant stacktraces or logs of your attempts?

The application's environment

Which versions do you use?

Additional information

ST-DDT commented 1 year ago

How do you access the server/resolve the address? It is likely that I'm unable to help you with this issue as this might have something to do on how grpc java handles connections. You might have to configure connection timeouts or request retry and for that you have to ask on the grpc-java repo or stackoverflow for help. If there is a property for that, that I could add support for please let me know.

Looks like there is nothing we can do here.

add the below configurations will help:

      enableKeepAlive: true
      keepAliveWithoutCalls: true
