Suddenly my PRTG web server is not available via its IP address any more, but instead I can only reach it via https://127.0.0.1 (resp. http://127.0.0.1). What happened?

This article applies to PRTG Network Monitor 9 or later

PRTG's IP Settings

If PRTG does not find a network card on startup it will switch the IP setting to Localhost, regardless of the configuration you entered before. This setting will remain, even if a network card is available later on.

So, for example, if you disabled or removed the network card on the machine running the PRTG core server, and PRTG did not find a network card on services start up, it might have changed the IP setting to use "localhost".

To check your settings, please log in to the machine running your PRTG core server, open the PRTG Server Administrator and check the settings in the Web Server tab. Change settings as needed.
