Hello @helloworld - welcome to the Percona Forums! It sounds like your PMM Server is running but you are unable to register clients. It would assist us greatly if you could download the diagnostic data from PMM Server and then attach to this issue so we can review and provide recommendations.

The http port is _only_ for browser interaction (so just accessing the UI). All client to server communication _must_ be over an encrypted channel…doesn’t necessarily need to be port 443 but does need to be HTTPS. so try the command: `sudo pmm-admin config --server-insecure-tls --server-url=https://admin: ******** @15X.X9.1XX.X06:8443` (note the https and change to the secure port…whatever you exposed when you did your `docker run` or setup from AMI/OVF. ---
