On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

Unable to open Plesk via hostname: Server not found

Plesk kb: technical ABT: Group A

Applicable to:

  • Plesk

Symptoms

  • Plesk is not accessible via hostname (https://example.com:8443) with the below error:

    PLESK_INFO: Server not found

  • Hostname is not resolved:

    # nslookup example.com
    ** server can't find example.com: SERVFAIL

    # nslookup example.com
    ** server cannot find example.com: NXDOMAIN

  • Plesk is accessible via an IP address (https://203.0.113.2:8443).

Cause

The hostname is not registered or resolves incorrectly on a registrar-side.

Resolution

Contact the domain registrar for assistance to make the domain name (hostname) resolve to the server IP address.

As a workaround, use the server IP address instead of the hostname:
https://203.0.113.2:8443
