If the ListenUnixSocket method is called before ConfigureEndpointsDefault with Http2 as Protocols in ConfigureKestrel, the following Exception is thrown by a client trying to communicate over that socket:

Call failed with gRPC error status. Status code: 'Internal', Message: '"Error starting gRPC call. HttpRequestException: The HTTP/2 server closed the connection. HTTP/2 error code 'HTTP_1_1_REQUIRED' (0xd). (HttpProtocolError) HttpProtocolException: The HTT P/2 server closed the connection. HTTP/2 error code 'HTTP_1_1_REQUIRED' (0xd). (HttpProtocolError)"'.

This can be solved by adding EndpointDefaults with Http2 as Protocols to your appsettings, or by changing the order in which the methods are called.
