Help

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: m1news.ru

I ran this command: certbot renew --post-hook “service nginx reload”

It produced this output: Processing /usr/local/etc/letsencrypt/renewal/m1news.ru.conf

Attempting to renew cert (m1news.ru) from /usr/local/etc/letsencrypt/renewal/m1news.ru.conf produced an unexpected error: Failed authorization procedure. www.m1news.ru (http-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: DNS problem: SERVFAIL looking up CAA for ru. Skipping.

IMPORTANT NOTES:

  • The following errors were reported by the server:

    Domain: www.m1news.ru
    Type: connection
    Detail: DNS problem: SERVFAIL looking up CAA for ru

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A/AAAA record(s) for that domain
    contain(s) the right IP address. Additionally, please check that
    your computer has a publicly routable IP address and that no
    firewalls are preventing the server from communicating with the
    client. If you’re using the webroot plugin, you should also verify
    that you are serving files from the webroot path you provided.

My web server is (include version): nginx/1.12.2

The operating system my web server runs on is (include version): FreeBSD 10.3-RELEASE-p21

My hosting provider, if applicable, is: Hetzner

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no
