How to manage SSL/TLS ciphers and protocols in Plesk for Windows?
For example, disable insecure ciphers and enable more recent ones.

Go to Start > Edit group policy.
Go to Local Computer Policy > Computer Configuration > Administrative Template > Network > SSL Configuration Settings > SSL Cipher Suite Order.
Set option Enabled.
Edit SSL Cipher Suites in the line.
