How to disable HTTP/2 on IIS of Windows Server 2016

We are running into some issues that seem to be affected by http2 and I want to turn it off temporarily to troubleshoot. I tried the registry keys outlined in this question but that did not help with Windows Server 2016.

  1. Start → regedit

  2. Navigate to the folder/path: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters

  3. Under the Parameters folder, right-click the white-space, add 2 new DWORD (32-bit) values:

    • EnableHttp2Tls
    • EnableHttp2Cleartext

  4. Ensure both new values have been set to 0(disabled) by right-clicking the value and clicking "Modify..."

  5. Restart the OS.

Another solution, if you are only testing, is run Chrome without http2 enabled. from start run, chrome --disable-http2

Also, apparently a fix is coming, we just have to be patient for the rollout. See THIS article
