That's not a perfect solution. The system will still check for updates, only the connection will fail.

If you want to disable ComfortUpdate to not get the New release available popup messages after each new release you can add the following option to your "config.php" file which can be found at /limesurvey/application/config (Always create a backup first!):
This is documented in more detail at " How to disable the Limesurvey ComfortUpdate updating feature ".
