This article applies as of PRTG 22

How automatic update notifications work

Auto-Update is a powerful feature that helps you keep your PRTG installation easily up to date. With each new version, we provide new features and bug fixes.

Which domains does PRTG connect to?

To check 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 go to Setup | Auto-Update | Status and click Check for Latest Update and Download, PRTG will connect to autoupdate.paessler.com to check if the license key is entitled to a free update. If yes, it will download the update from one of our download servers, 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 | Core & Probes (System & Website in previous versions).

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 address. However, this would of course disable the update notification and auto-update functionality.

Hello,

Thank you for reporting this mistake.

The Proxy settings are effectively available under System Administration | Core & Probes in the latest versions of PRTG, I have updated the links accordingly.

Regards.
