uptime user disconnects randomly

I am using Uptime Monitor version Uptime 7.8.2 

The monitor and dashboard are functional, but after 2 or 3 days ,   the admin user disconnect and you need to reenter the password to resume normal operation. 

I want that the session never log out or not as this  frequency.

how can i change this features ? 

  • Im Still Having this problem of random logout,  the user is superadmin, and logout from dashboard unexpectedly even if you have activity. 

    The Uptime is installed on windows server 2012.  Still no resolution.
