Hello @mukthiarahamad thanks for logging your issue. From the error it seems to be that you were just hitting a network issue when trying to download the base image for the 3.1 sdk, but that seems to be working for me now. Could you try again to see if this is now fixed?

Hi, I was able to resolve this issue. I have deployed the code in the azure container registry and have hosted it in a container. try to access the same from the client give me an error as below
Grpc.Core.RpcException: 'Status(StatusCode="Internal", Detail="Error starting gRPC call. HttpRequestException: Requesting HTTP version 2.0 with version policy RequestVersionOrHigher while HTTP/2 is not enabled.", DebugException="System.Net.Http.HttpRequestException: Requesting HTTP version 2.0 with version policy RequestVersionOrHigher while HTTP/2 is not enabled.
at System.Net.Http.HttpConnectionPool.SendWithRetryAsync

while I have enabled http2 in the server as below.

webBuilder.ConfigureKestrel(options =>
{
// Setup a HTTP/2 endpoint without TLS.
// options.ListenLocalhost(80, o => o.Protocols =
// HttpProtocols.Http2);
options.ListenAnyIP(5000, o => o.Protocols =
HttpProtocols.Http2);
});
webBuilder.UseStartup();
