Symptoms

Plesk users are using internet connection with dynamic IP which changes on every request. Plesk drops their sessions and displays a ‘session expired’ error message.

Resolution

1. Consider upgrading Plesk to the latest version

2. Insert the following record into the Plesk database, the ‘psa’ table, ‘misc’ database:
 
param='disable_check_session_ip', val='true'

Note: to turn it back remove the record or set val='false'
