How PRTG's Automatic Update Notifications Work

PRTG's automatic update downloads and notifications are powerful features that help you keep your PRTG installation up-to-date easily. With each new version we provide new features and bug fixes.

Which Domains does PRTG Connect To?

To find out if there is a new version available PRTG sends an HTTP request once every 24 hours (and once per restart) to:

http://updatecheck.paessler.com

If the update check finds a new version or if a user clicks on Download Now on the "Auto Update" page, PRTG will connect to

https://autoupdate.paessler.com

to find out if the license key is entitled for a free update. If yes, it will download the update from one of our download servers, usually

http://download.paessler.com

Can I Use a Proxy?

By default, PRTG will try to use a direct internet connection. If a proxy is mandatory in your network, please log in to the PRTG web interface and configure your proxy settings in the "System & Website" settings. For details about proxy settings, please see PRTG Manual: System Administration—System and Website

Can I Block this Traffic?

You could block this traffic by adding entries to the local hosts file that point to a non existent IP.

But this will kill the update notification and auto-update functionality, of course.
