how to check TLS version on Windows 2019 Datacenter, SCHANNEL error TSL 1.2

Question

Trying to confirm how you check the TLS version enabled on a Windows 2019 Datacenter Server.

Getting errors related to SCHANNEL and TLS 1.2, but from what I read TLS 1.2 should be enabled by default. I checked the registry keys no Protocols show up under the SCHANNEL key

Here is the error message I am seeing

SCHANNEL- An TLS 1.2 connection request was received from 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.

Answer 1

Hi,

If the registry is not there it means it is not enabled or some GPO or Update might have deleted the keys, I will suggest you to verify via the PowerShell script mentioned here. This is third party link but it should help you to verify.

Hope this helps.
