ePO installation fails due to SQL Server TLS cipher suite issue

[Childe57]

I have set up a Windows Server 2019 to for a fresh install of ePO 5.10.  I intend to leverage my existing  SQL server that is supporting our production ePO.  The installation rolls back while attempting to access the SQL server.  The SQL event viewer reports "A TLS 1.2 connection request was received by a remote client application, but none of the cipher suites supported by the client application are supported by the server.  The TLS connection request has failed".    I have checked\updated gpedit and registry keys on both servers, to no affect.  Any suggestions would be appreciated.

I used this tool to fixed this issue. https://www.nartac.com/Products/IISCrypto/

Everybody swears by that tool.  Unfortunately, I am in an environment where access to that vendor and its tools are blocked.

I was able to use IISCrypto on the system.  Changes made using the tool are not being retained after rebooting.

That would indicate some gpo is reverting changes.  KB91519 lists out all the required ciphers and schannel settings and also breaks it down for CU requirements.

I started over with a fresh Server 2019 and the IISCrypto tool worked as expected.

My issue was resolved.  I update my cipher suite to the current list supported by Server 2019
