I keep getting 404 when I tried accessing the "http://localhost:8081/artifactory", does anyone else faced the same issue?

Logs shows:
Cluster join: Retry 405: Service registry ping failed, will retry. Error: I/O error on GET request for "http://localhost:8046/access/api/v1/system/ping": Connection refused

Which I installed and configured the PostgreSQL however, the logs keep showing the same things, which is very annoying... I must be missing something.

I've also tried installing on Ubuntu 22.04 using different Artifactory version just to test but still same errors. What am I missing?
