How Automatic Update Notifications Work

Auto-updates of PRTG are powerful features that help you keep your PRTG installation up-to-date easily. With each new version, we provide new features and bugfixes.

Which Domains Does PRTG Connect To?

To find out if a new version is available, PRTG sends an HTTP request once every 24 hours (and once per restart) to updatecheck.paessler.com.

If the update check finds a new version, or if you click Check for Latest Update and Download under Settings | Auto-Update | Status, PRTG will connect to autoupdate.paessler.com to find out if the license key is entitled to a free update. If yes, it will download the update from one of our download servers, which is usually 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, log in to the PRTG web interface and configure your proxy settings under Setup | System Administration |User Interface ("System & Website" in previous versions). For details about proxy settings, see PRTG Manual: System Administration—User Interface.

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