Questions:

1. Why are the cipher configuration properties not being recognized in the 
connector configuration?

No idea. Your organisation wrote the protocol implementation. That would be a question for your development team.

I will note that is that were a standard Tomcat connector, that configuration will not work as that configuration style for TLS was deprecated in Tomcat 9 and removed entirely in Tomcat 10.1 and 11

I'll further note that the custom Connector appears to be trying (and I guarantee it will be failing) to encrypt some Connector settings.

If you really need to implement such pointlessness, I'd suggest using the PropertySource approach rather than implementing your own protocol - it will be a lot less susceptible to changes in the Tomcat code base.

2. Are there any Tomcat security policies that override explicit cipher 
configurations in server.xml?

No, but given that this isn't a Tomcat connector, that is the wrong question, sent to the wrong people.

3. If there are security configurations that disable certain cipher suites 
(particularly RSA key exchange ciphers), could you please provide:
    * The specific configuration files or properties involved
    * Documentation on how these security policies work
    * Methods to override or customize these policies if needed

N/A.

4. What is the correct way to explicitly control cipher suites in Tomcat to 
ensure only our specified ciphers are available.

Again, a question for your internal development team that wrote the protocol implementation you are using.

Mark
