Hello there,

It seems that the web server port 443 used by another application therefore, it's unable to modify the settings in PRTG web interface. Please restart the PRTG server and afterwards try again to change the dns name. Does it helps?

port 443 used by prtg only, so I found a workaround I think. I disable all IPs except 127.0.0.1, after that I restart server and change dns name, then I enable the serving IPs again, it works like that. thanks
