    Final resolution:

    Download IIS Crypto (https://www.nartac.com/Products/IISCrypto/

    Add the following Keys to the 1st and 2nd position respectively (they weren't there on 2 servers I've tested so far)

    TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384

    TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

    Find and move the following keys to the 3rd and 4th position respectively (they are there but not in the right order)

    TLS_DHE_RSA_WITH_AES_256_GCM_SHA384

    TLS_DHE_RSA_WITH_AES_128_GCM_SHA256

     



    Make sure all of the check boxes are selected, press Apply, reboot the server.
