DNS issue: Incorrect validation certificate for tls-sni-01 challenge


  • The following errors were reported by the server:

    Domain: samentweedehandsshop.eu
    Type: unauthorized
    Detail: Incorrect validation certificate for tls-sni-01 challenge.
    from Received 2 certificate(s), first
    certificate had names “stopkindermisbruikdot.eu,

    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.

This means that you do not have an A Record pointing from your domain to the server IP. You will need to add that with your domain registrar.
