There was an error downloading metadata from the address

Question

I am trying to add service reference.

There was an error downloading metadata from the address

this is the error which is being displayed again and again?

Answer 1

I had an issue like this one : Adding a service reference failed with a message "Method not allowed".

The wsdl worked fine in my browser..

The reason was that I configured the endpoint to listen on http://0.0.0.0:6000/mex, which the "Add Service Reference" tool doesn't seem to like. Changing it to a real IP address made it work (e.g. http://127.0.0.1:6000/mex)
