I’ve had LE certificates for over a year now, so this isn’t a new certificate problem. I get the error when running certbot renew:
FailedChallenges: Failed authorization procedure. silverbacknetworks.tech (http-01): urn:acme:error:unknownHost :: The server could not resolve a domain name :: No valid IP addresses found for silverbacknetworks.tech
I have double-checked that my nameserver has * set to an IP address (22.214.171.124), and that it’s resolvable via dig and curl on my end. The DNS entry hasn’t changed in months, so it shouldn’t be a propagation problem. Anything I can do? Or should I just wait and see if it works later?
