Incomplete Authorizations error when trying to renew

Your domain’s DNS seems to be misconfigured right now. It is pointing at some AWS Route53 nameservers, but those Route53 nameservers return REFUSED when queried for your domain.

I would try fixing your nameserver situation first and then seeing what happens with another --dry-run.

There have been some instances in the past where issues like network timeouts were a little racey and caused weird errors to be spit out of Let’s Encrypt/Certbot, but they were masking underlying issues with the domain name or webserver being issued.

So hopefully fixing your DNS should either fix everything, or unmask the underlying problem.

Late Edit: I believe this thread is a report of the same issue.
