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.

Symptoms

  • Site served by CloudFlare shows:

    CONFIG_TEXT: 522 error
    Connection Timed Out

    or:

    CONFIG_TEXT: ERR_CONNECTION_TIMED_OUT

  • If site is resolved to a Plesk IP in the hosts file (without CloudFlare involved into processing the request), it displays correctly.
    Or, it may show SSL warning:

    CONFIG_TEXT: Your connection is not private
    This server could not prove that it is example.com; it's security certificate is not trusted 

Cause

CloudFlare blocks connections to sites with untrusted SSL, or domain's DNS are setup incorrectly on CloudFlare side and A record points to a different server

Resolution

Contact CloudFlare support for assistance.

    Hello @FeteDayz iRadio,

    This article is devoted to certain symptoms, so if the cause of the issue is different, another article should be used to solve it.
