PRTG Manual: SSL Certificate Warning
This section was moved and is no longer kept up to date. For more information, see the Knowledge Base: Why does my browser show an SSL certificate warning when I open the PRTG web interface?.
If you use PRTG Network Monitor outside your internal LAN, in particular if you use it on the internet, you should set the PRTG web server to use SSL/TLS. Your browser then shows an SSL certificate warning because PRTG comes with a self-signed certificate. The connection to your PRTG web server is secured with SSL/TLS anyway and you can confirm the claimed security risk.
Every browser shows a slightly different SSL certificate warning that you need to confirm to proceed:
In Google Chrome, click Advanced, then click Proceed to [yourPRTGserver] (unsafe) every time you open the PRTG web interface.
In Mozilla Firefox, click Advanced, then click Accept the Risk and Continue.
You only have to take these steps once for every Firefox browser session and PRTG core server.
In Internet Explorer, click Go on to the webpage (not recommended) every time you open the PRTG web interface.
The procedure is similar for other browsers that are not officially supported.
Why can't I save my PRTG password in Google Chrome?
