[ERROR] Failed authorization procedure; The server experienced a TLS error during DV

Server

Hi,

I got invited to beta and tried creating certs for my beta domains. The cert creation for 2 of 3 domains worked properly. But with my 3rd domain I get the following error:

Failed authorization procedure. www.###.net (dvsni): tls :: The server experienced a TLS error during DV :: Failed to connect to host for DVSNI challenge, ###.net (dvsni): tls :: The server experienced a TLS error during DV :: Failed to connect to host for DVSNI challenge

IMPORTANT NOTES:

  • The following ‘tls’ errors were reported by the server:

    Domains: ###.net, www.###.net
    Error: The server experienced a TLS error during DV

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A record(s) for that domain contains
    the right IP address. Additionally, please check that you have an
    up to date TLS configuration that allows the server to communicate
    with the Let’s Encrypt client.

It was all on the same server; the configuration for all domains is identical. The A-DNS record is correctly set.

Any clue or how to dig into this?

Kind regards

Update: I don’t know why, but now it worked.

Well, just got the same. But don’t know what it means and how to fix it.

Any chance that either of you are behind a service like CloudFlare? If so, you’ll want to temporarily disable it during the issuing of the certificate.
