Synergy/TeacherVUE: Getting "Kicked Out" Frequently

Last modified on 04/03/2020

What to do if Synergy freezes, kicks you out, or generates error messages after a short amount of idle time.

Synergy is set to take users to a lock screen after they have been idle for over an hour. This is to protect confidentiual student data. From the lock screen, the user simply re-enters their password to get back into the system.

Some users, however, are finding that Synergy will "freeze" on them and generate error messages after a short amount of idle time, often just over 15 minutes. They are then unable to do anything in the system and have to quit their browser to get back in to Synergy.

This article will show you how to change settings on your Mac to avoid this problem. Note: this may help with other network related issues as well.


1. Open System Preferences under the Apple menu
