The problem for this user was content negotiation: https://learn.microsoft.com/en-us/aspnet/core/grpc/aspnetcore?view=aspnetcore-8.0&tabs=visual-studio#protocol-negotiation

There is nothing specific about docker to their problem. They just happened to be using TLS locally (which did content negotiation) and not use it in Docker.

Possible changes?

• A trouble shooting section that mentions HTTP_1_1_REQUIRED that links to the protocol negotiation section could be added.
• Adding more detail to the protocol negotiation about what changes are required rather than just linking to Kestrel docs.
