GitHub user mengwuzhi added a comment to the discussion: Problem encountered during client connection
I'm not very sure if it is a problem with my server, It happened in both production and development environments simultaneously. I can test but no touch with the production server. On my own server, I can view both the broker and namesrv logs. However, I'm not very sure whether the endpoint should be set to the broker's port number or the server's port number. Actually, no issues can be seen in the broker log, but after I set the endpoint to the namesrv's port, I can see an error in the log. It says  I don't know why I was just registering as a consumer, but the frame length i too long to be discarded.
