Server

IP Address for PRTG Web Server on the PRTG Web Server tab

For connections to PRTG Hosted Monitor instances, this is the domain name.

For more information, see the PRTG Manual: PRTG Administration Tool on PRTG Core Server Systems.

Port

TCP Port for PRTG Web Server on the PRTG Web Server tab

PRTG switches to port 8080 as a fallback after a restart when port 80 is already used, and to port 8443 if port 443 is not available. PRTG keeps the Secure Sockets Layer (SSL) connection in this case. If this port is also not available, PRTG tries from port 8081 (8444 for SSL) on until it finds an available port.
Because the PRTG app for desktop cannot automatically recognize these ports (8080+, 8443+), manually enter the used port in the Port setting when you add or edit an account in the PRTG app for desktop. If you do not get a connection to the PRTG web server, also check the used port in the PRTG Web Server settings under System Administration | User Interface in the PRTG web interface.

For connections to PRTG Hosted Monitor instances, this is 443 by default.
