vRA Security hardening - TLS1.2 missing step

After a few attempts to harden my distributed vRA environments (7.3 and 7.4), running through the steps of the appropriate security hardening guide, with no success, I was able to finally identify the missing information that drove me up the wall.  After implementing the steps identified in the hardening guides, the infrastructure tab would not display and gave a 404 error.  In hopes of saving others this pain, refer to this KB article which will save you hours:https://kb.vmware.com/s/article/2146570?lang=en_US . The missing piece is Enable the "SchUseStrongCrypto" property in the Windows registry to enable dotNet to use as default TLS 1.0+ protocols.  After a quick reboot, I finally had a functioning infrastructure tab!
