Hello,
got an email today from LetsEncrypt:

Betreff: Let's Encrypt certificate expiration notice for domain "xxx,yyyy,zzz" (and 2 more)

Hello,

Your certificate (or certificates) for the names listed below will expire in 6 days (on 2024-10-28). Please make sure to renew your certificate before then, or visitors to your web site will encounter errors.

We recommend renewing certificates automatically when they have a third of their total lifetime left. For Let's Encrypt's current 90-day certificates, that means renewing 30 days before expiration. See https://letsencrypt.org/docs/integration-guide/ for details.

Where could I see the end date auf certificates in NS8?
Under NS7 this was no problem

I found no easy way. You could use the traefik cert dumper tool to extract the certs and get the dates on command line:

for f in *; do openssl x509 -subject -enddate -noout -in $f; done

Usually you shouldn’t get these mails, the certs should be renewed automatically. Is the domain name set correctly in DNS?
