Here are five ways you can use to fix the SSL Handshake Failed error: Update your system date and time. Check to see if your SSL certificate is valid (and reissue it if necessary). Configure your browser to support the latest TLS/SSL versions. Verify that your server is properly configured to support SNI.
If you run Wireshark on the PVWA while making the request, you'll see that the server indeed sends a "Client Hello" (via TLS 1.0) to ServiceNow, but it replies with a "Fatal Error: Handshake Failure", since it only accepts TLS 1.2.
