Error requesting certificate

Help
1

My domain is:southbankyoga.co.uk (pings to 173.212.199.13 which is correct
Ubuntu Linux 20.04.3
certbot 0.40.0
Apache2
letsencrypt.txt (199.7 KB)

I can login to a root shell on my machine (yes or no, or I don't know):yes but can't run certbot
(certbot does not know how to configure this server etc - but it works fine using virtualmin)

Hi I am migrating sites to a new server and I have already moved 40 without a problem, I am using virtualmin to request the certificate.

When I tried to this site I got the error below

I ran this command: Virtualmin - add SSL from letsencrypt

It produced this output:Saving debug log to /var/log/letsencrypt/letsencrypt.log

Seems the DNS resolving capabilities of this server are inadequate.

Yes, it would seem so because I tried with another site which also failed with the same problem. This VPS has 40 sites and has worked fine up to now. So is there a limit?

This is not an error produced by the Let's Encrypt validation server, but by the client on your server. So I don't know why this happens? Can you retrieve the URL https://http://acme-v02.api.letsencrypt.org/directory through other clients such as curl or wget on that same host?

This error is usually transient, is it still there?
