I’m getting a “DNS problem: NXDOMAIN looking up A” error when trying to update a certificate. It’s using ubuntu / nginx.
ubuntu@ip-172-30-0-32:~$ sudo letsencrypt renew
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Cert is due for renewal, auto-renewing…

Cleaning up challenges
Attempting to renew cert (manage.stage.nowbackto.me) from /etc/letsencrypt/renewal/manage.stage.nowbackto.me.conf produced an unexpected error: Failed authorization procedure. manage.stage.nowbackto.me (tls-sni-01): urn:acme:error:dns :: DNS problem: NXDOMAIN looking up A for manage.stage.nowbackto.me. Skipping.
All renewal attempts failed. The following certs could not be renewed:
1 renew failure(s), 0 parse failure(s)
Are there particular configuration files I should be editing and with what? I’ve seen similar posts on here using dig but I’m not sure what to use there.
