Stuck on an issue?

Lightrun Answers was designed to reduce the constant googling that comes with debugging 3rd party libraries. It collects links to all the places you might be looking at while hunting down a tough bug.

And, if you’re still stuck at the end, we’re happy to hop on a call to see how we can help out.

GPRC server/client test.

See original GitHub issue

I was following tutorials on microsoft documentation pages, everything worked except making the call itself, the error states :

Grpc.Core.RpcException: 'Status(StatusCode=Cancelled, Detail="Bad gRPC response. Expected HTTP status code 200. Got status code: 426")'

I guess this has something to do with the HTTP2.0 protocol ? I have created a repository with my example code at : https://github.com/christophedemey/gprc

Any help is greatly appreciated. Kind regards Christophe.
