Add support for TLS 1.2 in Visual Studio 2015 Enterprise Web Performance Tester

Our security policies are mandating use of TLS 1.2. When attempting to script and playback a web performance test I received an SSL error. Only by adding a coded plug-in supplied by MSDN support was able to get it to work. Going forward support for TLS 1.2 should be included "out of the box"

    Hi Phillip & GezaSoos,

    I have added these entries on my Reg edit file. But still i am facing the "Request failed: An existing connection was forcibly closed by the remote host".

    This was EXACTLY the fix I'd spent almost a week trying to do..and with no need for a VS test plug-in. Thanks! For me, I was testing SharePoint 2016 sites, of course using HTTPS, and I'd been having similar redirect errors to everyone else. This got me going.

    The registry fix provided by @GezaSoos solved the problem for me! it also fixed Excel being unable to connect when TLS 1.2 was enabled.

    Thanks for this! I was having issues with previously working webtests failing in VS2017 ("Request failed: An existing connection was forcibly closed by the remote host"). Despite my projects using .NET Framework 4.7.1 the tests were failing until I added the two registry entries.

    We are using TFS 2015 Update 4. We can't connect to TFS from client versions MTM 2015, VS 2012, GitBash and Excel Plugin aren't working with TLS 1.2 only. We got it working when enabled TLS 1.0 & TLS 1.2. Enabling TLS 1.2 & TLS 1.1 aren't doing anything.

    Try this on the client:

    Windows Registry Editor Version 5.00



  • Jeff Blankenbiller commented  ·   ·  Flag as inappropriate

    We have TFS 2015 Update 3 and we have disabled TLS 1.0 on the server.

    We can't connect from MTM 2015.

    Please add support for TLS 1.1 and TLS 1.2 to MTM.
