A few things.
If you want TLS access to Artifactory, the best option is to set up a Nginx server in front of Artifactory (even on the same machine) and have the ssl termination handled by it. Artifactory can generate a nginx config snippet to make this set up very easy. See here: https://jfrog.com/help/r/jfrog-artifactory-documentation/reverse-proxy-settings
Turning on TLS is only if you must have internal TLS communication and is generally not needed.
I want to clarify. You currently have access on 8082 over http? or https? If it is http, then I suspect the access.config.import did not work to enable TLS.
