article Login screen returns Database not responding error after upgrading

If you did not log out of the up.time UI before upgrading (refer to step 5 of Upgrading to up.time 7.2 of Later), you may see the following error after attempting to login after the upgrade:

 

Database is not responding...

To resolve this issue, you can force the logout by navigating to: http://servername:9999/main.php?logout=1 where servername:9999 is the name of your server and the port you use to connect to up.time.

 

Other options to clear the issue include:

  • Clear the cache and restart the browser.
  • Reboot the server.
  • Click the logout button (if visible).
