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

Plesk for Windows Plesk for Linux kb: technical Ideal

Applicable to:

  • Plesk for Linux
  • Plesk for Windows

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 to access Plesk, is behind a proxy server (for example, Cloudflare).

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

Resolution

Allow IP address changes during a single session:

Plesk interface
  1. Log in to Plesk (if it is not possible to log in using the hostname, use the server's IP address).
  2. Go to Tools & Settings > Session Idle Time (under Security section).
  3. Enable the option Allow IP address changes during a single session.
  4. Click OK to apply the changes.



     

Command-line interface
  1. Connect to your Plesk server via SSH (Linux) / RDP (Windows Server).
  2. Enable IP address changes during a single session:

    Note: On Windows Server, start a command prompt as an Administrator):

    # plesk bin settings --set disable_check_session_ip=true

  • Morning, I am having the same issues stated in this article, I have applied the fix via SSH, however this has not resolved my issue.

    I have not changed IP's during the session and I have connected to our office VPN, which has a static IP and does not change, yet the issue still continues.

    I have restated the server, to ensure there we no locked files etc, and this too has had no effect. I log in, click subscriptions, then get redirected to the log in page, it doesn't matter what option I select, I keep getting sent to the log in page
