I’m getting Timeout on all domains I’m trying to install certs on:
Failed authorization procedure. BOOP.se (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Timeout, www.BOOP.se (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Timeout
The domains are live and working well, but:
2017-11-04 13:50:36,373:DEBUG:certbot.reporter:Reporting to user: The following errors were reported by the server:
If you hide the real domain then we can only provide guesses.
If you provide a real domain then we can do a real investigation and propose an adequate solution.
So here is my GUESS:
You have IPv4 and IPv6 for your domain and the IPv6 is misconfigured.
And as LE prefers IPv6 over IPv4, it will continue to fail until you correct the IPv6 problem or remove IPv6 records from DNS.
How did I do?
And your lucky lotto numbers are: 17, 42, 69, 3.14, and -1.
