I've been seeing an error in our GeoEvent logs that states "ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN".  The error is related to our server's message bus platform service.  The error usually starts showing up after our server reboots but we sometimes are able to connect after a normal startup procedure.  We are able to fix the issue by stopping the message bus and then restarting it but this process can and usually takes 5 or more attempts.  We updated our startup routine so that the Gateway waits to start until two minutes after ArcGIS Server and GeoEvent waits until two minutes after the Gateway has started.  The issue still persists after adjusting the startup procedure.  These seems tricky to pinpoint as restarting the message bus enough times will resolve the issue.  The logs are also throwing two errors related to an "unexpected connection driver error" and one from RabbitMQ that states "the trust manager trusts every certificate, effectively disabling peer verification".  I've attached a snapshot of the logs.  We are running 10.6.1.
