Hi, what does below error mean ?

rpc error: code = DeadlineExceeded desc = received context error while waiting for new LB policy update: context deadline exceeded

[vadimi]

hello, the error is coming from grpc-go connectivity code - it means that it failed to connect to the service, most likely it's not accessible

received context error while waiting for new LB policy update:

This seems too internal , is it that load balancer is not able to pick a channel ? what is it? I am able to ping my grpc server port , btw it worked fine for one of my grpc server , Thanks for the amazing tool

[vadimi]

it's hard to tell what's going on in your environment - is your service behind some sort of proxy/load balancer? the port could be open, but if http/2 protocol is not properly exposed then it will cause connectivity issues.

Hi @vadimi does the tool support secure mode? Does it require an SSH key or any other configuration for TLS? It's possible the error is related to running it in secure mode.

[vadimi]

yes, it does, if you run it with grpc-client-cli --help it will show the flags you need to pass: --tls, --cert, --certkey depending on your use case
