I did 5 days ago, the registration of the domain name but still unavailable the website. It say "Issuing TLS Certificate" not sure why some many days waiting, any idea someone please.

The steps that i dis was:

Settings>Networking>Public Networking>Custom Domain

This likely means something was done wrong, please remove and re-add the domains.

Brody, i did again just now, i set now port: 8080. How long should wait, till 72 hours ?
