Add service reference from Visual Studuio

Question

when I try to add a web service reference appear this window:

Will this be a blocking error when i call the webservice from code?

When I call a method of the webservice I get the following error: Request canceled: Unable to create SSL / TLS secure channel.

Can this error be related to the problem in the image? Tank you

Answer 1

This error usually happens when you are accessing a HTTPS site without proper SSL certificate. If you know the service and what you are doing, like when you have a local HTTPS service you can disable SSL verification, and you should be fine then.
