Disable TLS 1.0/1.1/1.3 Protocol
If the outdated TLS protocols 1.0 and 1.1 need to be disabled, because TLS version 1.2 is considered significantly more secure.
Disabling the TLS Protocol v1.0, v1.1, and v1.3 may cause an issue with 'Email Triggers' from Nintex Console for RPA version 22.9.2 due to a TLS protocol mismatch.
Instructions

4. Change the Enabled value to 0 and the DisabledByDefault to 0xffffffff.
