Try also executing the below powershell command in an attempt to ensure any Windows default scripts that run use TLS1.

Ensure your internet explorer options only use TLS 1.2 in case that app is used as a basis for something. Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the 'Applies to' section. You can configure the Client registry values on the client devices to only use TLS 1.2 and configure the WSUS server registry value to only use TLS1.2 and see if that prevents those events from showing. If it is just a WSUS server it could be caused by the clients as well maybe.

What else is using TLS on that server? I would say look at each service using TLS and disable one or more of them to see if any of the combos prevent the event from showing up. Do you have RDP configured to use TLS and is the RDP certificate using a strong enough key for TLS or is the key size too small causing a self signed certificate to be generated and assigned to the RDP port? You can also force the use of a specific RDP template to ensure the one you want is utilized.
