Question: Login to Plesk from WHMCS redirects to Plesk login page instead of logging in.


Applicable to:

• Plesk for Linux

Symptoms

• SSO connection to Plesk though WHMCS fails. Login to Plesk from WHMCS redirects to Plesk login page back instead of logging in.

• WHMCS is behind Cloudflare,

Cause


User's IP address is changed during a Plesk session. This may happen if user's IP address is dynamic or the domain/hostname which is used as a URL for Plesk is behind Cloudflare.

By default, Plesk does not allow IP address changes during a single session.


Resolution

Allow IP address changes during a single session:

1.Log in to Plesk (use the server IP address if it is not possible to log in using the hostname).

2.Go to Tools & Settings > Session Idle Time and enable the option Allow IP address changes during a single session.

3.Click OK to apply the changes.
