A user is being logged out from Plesk periodically or Plesk redirects to the login page after a successful login attempt

Symptoms

A user is being logged out from Plesk periodically when navigating between pages in Plesk interface.
Plesk redirects to the login page after a successful login attempt.

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:

Log in to Plesk (use the server IP address if it is not possible to log in using the hostname).
Go to Tools & Settings > Session Idle Time and enable the option Allow IP address changes during a single session.
Click OK to apply the changes.

Command-line instructions

Connect to the Plesk server via SSH (Linux) / RDP (Windows Server).
Run the following command to enable IP address changes during a single session (on Windows Server, start a command prompt as an Administrator):
# plesk bin settings --set disable_check_session_ip=true
