Hello,
In this particular situation "unauthorized root" indicates that your 192.168.1.201 device refuses the authentication, while "port 443 refused" indicates that your 192.168.1.201 device is probably not listening on 443 port and is only accepting connection via port 80.
Your encountered issue seems to be related purely with your 192.168.1.201 device or with command which you are trying to use, and should not be caused by your RUT240.
Regarding the command itself, do not put your token between "< >" symbols, or convert it from Base64 to plain text and use "curl --anyauth --user daniel:secret http://example.com/" instead.
