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 | Core & Probes ("System & Website" in previous versions). For details about proxy settings, see PRTG Manual: System Administration—Core & Probes.
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.

I can't find the proxy settings in the Setup | System Administration |User Interface that this article mentions. Where are the proxy settings?

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.
