dnsdomainshostinghosting settingshttps

Symptoms

  • The SSL certificate is set in Plesk > Domains > example.com > Hosting Settings.
  • In an attempt to access https://example.com the SSL warning or another SSL certificate is shown.

Cause

The incorrect IP address is set for the A record of the example.com domain on a DNS Registrar/external DNS server side.

Resolution

  1. Log into the server via SSH.
  2. Execute the command below to find the external NS servers of the example.com domain:

    # dig +short example.com NS

    ns1.testdomain.tld.
    ns2.testdomain.tld.

  3. Contact DNS Registrar/administrator of the external DNS server(where the found NS from step №2 are located) with the request to point A record of the example.com to Plesk server IP address.

Note: the process of DNS propagation can take up to 48 hours.
