Are you logging in on the publisher first?  If not, I would check the Sling Authentication Service in the OSGi console is set to allow Anonymous access. https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/aem-sites-locked-for-anonymous-users/td-p/260595

Is this an adobe hosted cloud environment, or self hosted AWS/Azure environment?  The JMX console will be most likely secured and inaccessible by design.  I would deploy the prod packages to a lower environment and try connecting there.
