So today i was reciving this email from Lets Encrypt, that my certificates will run out. So i was checking my Cronjob that i configured, to automaticly renew the certificates.All Fine.
After that, i ran the command mannually and becate the following output:
Attempting to renew cert from /etc/letsencrypt/renewal/justingrah.me.conf produced an unexpected error: Failed authorization procedure. www.justingrah.me (tls-sni-01): urn:acme:error:unknownHost :: The server could not resolve a domain name :: No valid IP addresses found for www.justingrah.me. Skipping.
I’m running Apache 2.0 with PhP 7.0 on an Debain 8.0 Jessie.
I recently created an reverse DNS record for my mailserver. Can this be an problem?
Or did I messed up the DNS Configuration? (See Table below
- TXT v=spf1 a aaaa mx ptr ~all
