What problem are you trying to solve?

[michaelklishin]

We cannot suggest anything with this much information.

Besides, I guess, the fact that to disable the non-TLS AMQP listener you can use rabbitmq.conf:

# disables non-TLS listeners, only TLS-enabled clients will be able to connect
listeners.tcp = none

Our community support policy is very explicit on the fact that we won't troubleshoot TLS and networking for non-paying users.

There are dedicated doc guides for both.
