Setting up mastodon (letsencrypt firewall error)

I’m trying to set up a mastodon instance using the 1-click droplet on the marketplace.

I can SSH in and run most of the wizard, but I can’t get a certificate as it keeps saying “likely firewall error”

I’ve tried opening ports 80 and 443 using ufw, and setting a firewall to allow these in the DO dashboard.

DNS are setup as per the instructions, and checkyourwebsite is showing some strange stuff: A has the IP and details, but AAAA is blank has a Name Error

* has Name Errors for A, AAAA and CNAME

All have is Auth = yes.

What’s going on here? This is the first time I’ve tried to deploy anything and I’m hitting a brick wall.
