On-Premises Guide faulty link "Ingress bare metal instructions"

[marcel1337x]

Describe the bug
While following the on-premises guide in the "Ingress" section when clicking the link under "If you are on bare metal you could try these instructions"

I am greeted by a faulty tls certificate. When accepting it, I am redirected to "503 Service Unavailable No server is available to handle this request."

To reproduce

1. Go to https://jenkins-x.io/v3/admin/platforms/on-premises/
2. Scroll down to the "Ingress" section and click the last link
3. Accept faulty tls certificate

Expected behaviour
To see instructions for a bare metal deployment

Upon further analysis it seems like the whole Server experiences problems
