Hi,
I saw there are many posts on the same issue, but they were not helpful.
I have installed Discourse using DigitalOcean’s Marketplace.
I’m having this error
Checking your domain name . . .
WARNING: Port 443 of computer does not appear to be accessible using hostname
Within from droplet I was able to confirm

I have a record in DNS settings and able to ping the domain name.
I added the record in DNS almost at the same timing I was creating a droplet.
I understand it usually may take up to 24 hours, but it seems the domain is being resolved.
