If you find that MDrivenServer or the Turnkey server can't call an API and you get error messaging pointing to connection problems because of SSL/TLS, please refer to this:

• Use https://www.ssllabs.com/ssltest/ to find out which protocols are available at the endpoint you are calling
• Use https://clienttest.ssllabs.com:8443/ssltest/viewMyClient.html in Internet Explorer (as of November 2020) to discover which protocols your Windows installation supports.

You can then use https://www.nartac.com/Products/IISCrypto/ to add protocols to find a matching set of protocols for the two servers to use.
