Terminated instance with certs on it. Now I can't create new ones?

My domain is: timder.app

I ran this command: sudo certbot certonly --standalone -d timder.app -d www.timder.app

It produced this output: Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
Domain: timder.app
Type: connection
Detail: 140.82.39.132: Fetching http://timder.app/.well-known/acme-challenge/Lt4f61zD3aYEwtw3BJyrBXsip71XcW-vmWKpEM6nL5M: Timeout during connect (likely firewall problem)

Domain: www.timder.app
Type: connection

Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 80. Ensure that the listed domains point to this machine and that it can accept inbound connections from the internet.

The IP is the address of the old instance that I terminated.

What can I do?

Make sure port 80 is open on any server firewalls. It doesn't look like it's open.

Is that the same IP address as your new instance? Or do you need to change the DNS to the new IP address perhaps?

Thanks I didn't realize I had to change the DNS to point to the new IP.

Once your IP address changed, without a DNS update your entire site wasn't reachable any longer. So it wasn't just required for getting a certificate, it was required for the entire operation of your website :slight_smile:
