Thank you for reporting.
Repositories on download.jboss,org have been moved from http to https, I have tried https://download.jboss.org/jbosstools/photon/stable/updates and it works.
You can also try Eclipse 2019-06 for Java EE and JBossTools 4.12.0.Final.
If you still experience issues, please create JIRA: https://issues.jboss.org/projects/JBIDE

Please advice on this issue.
Thanks for reporting.
If you want to use Eclipse 2019-06 for Java EE you should use JBossTools 4.12.0.Final from this update site:https://download.jboss.org/jbosstools/photon/staging/updates/ .
Please let me know, if you have any issues.

I was able to resolve the issue. I believe my company had some Security Certificates that were not friendly with JBoss Tools. After reinstalling some of my Certificates from an older & working machine against the JDK of my new laptop (run keytools in command prompt), I was able to successfully install JBoss Tools 4.5.3.Final on Eclipse Oxygen.
