BizTalk Connectivity Issues with WCF Custom Adapater over HTTPS connection RRS feed

  • Question

  • Hello,

    We are using BizTalk Server 2013 to connect to a web service over HTTPS url. The web service call failing with below errors.

    Error Description: System.ServiceModel.Security.SecurityNegotiationException: Could not establish secure channel for SSL/TLS with authority.

    The request was aborted: Could not create SSL/TLS secure channel.

    The same web service call works with SOAP UI and response is received. 

    Please let me know if you have encountered this and any suggestions..

    Thank you.

  • Try browsing to the web service and see what version of TLS it uses.

    If it is TLS 1.1 or TLS 1.2 you will have to either

    1) Install Cumulative Update 7  and follow the steps that are linked to from the Support for TLS 1.2 by changing registry entries to make .Net start negotiating with TLS 1.2 and falling back to older version.

    2) Write a custom end point behavior where you can explicitly set the TLS version to use.
