Why does Plesk show a warning about access to the foreign subscription is denied?

Question

Why does Plesk display the warning “Access to the foreign subscription is denied”?

PLESK_WARN: Access to the foreign subscription is denied

Answer

This warning can appear when a user accesses certain areas of the Plesk interface (such as File Manager or Backup Manager) while the Plesk session has expired, especially when using a direct or bookmarked URL. 

In this situation, Plesk cannot determine the active session and subscription context, so the access-checking controller displays the warning. This does not indicate a real permission or subscription issue, does not affect Plesk functionality, and can be safely ignored. Logging in again and accessing the feature through the Plesk UI resolves the message.
