Get stuck at the

Please wait until PRTGs web server is running...... Connecting to: http://127.0.0.1/group.htm?id=0&tabid=1 failed...: HTTP/1.1 401 Unauthorized

Hi there,

Please make sure that no AntiVirus is preventing PRTG from starting. Please also make sure that there is no other webserver running on the same server as PRTG. Additionally, check the "Web Server"-Tab in the "PRTG Administration Tool" on the Core Server that the settings are correct.

Best regards.
