BizTalk wcf-webhttp

System.ServiceModel.Security.SecurityNegotiationException: Could not establish secure channel for SSL/TLS with authority ''. ---> System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.

I am getting the above error when trying to communicate with the rest API with WCF-WebHTTP adapter in the send port. It was working fine and started throwing this error. When browsed in the browser I am getting warning msg as below.

The security certificate presented by this website was issued for a different website's address.

Hi There,

Thank you for asking this question on the Microsoft Q&A Platform.

Please mention the BizTalk server Server as well.

This issue could be because of multiple reason, either the end point has some change and now requires TSL 1.1. or TLS 1.2. Check with the partner/client why you are getting the warning msg. If it is a certificate error, you need to resolve that. As you said it was working so I suspect something changed as cert level or endpoint level.

If it is a higher TLS you either need to set some registry entries to make .Net 4.5 default to TLS 1.1 or TLS 1.2, or you need a custom Endpoint Behavior to set it in the port.

See this article for example. https://social.technet.microsoft.com/wiki/contents/articles/51476.biztalk-configure-tls-1-2-on-biztalk-server.aspx
