Title How to enable TLS1.2 for .net framework on IIS Web Server      
Resolution

Issue: .NET application pool attempts to establish an SSL/TLS connection to a third-party service or API and encounters errors.

Possible Errors:

  • The client and server cannot communicate, because they do not possess a common algorithm.
  • Could not create SSL/TLS Secure Channel.

Resolution: To resolve the above issues, follow these steps:

  • Copy the script text and save as enabletls12.ps1 and testtls.ps1 on the web server, example directory C:\support.
  • Run the scripts from elevated powershell on the IIS server where the .NET application pool is hosted.
    • Example: cd c:\support
    • .\enabletls12.ps1
    • .\testtls.ps1
  • Your test output should look like the following screenshot.
  • Test your web application again to see if the errors are resolved.EnableTLS12.ps1
