Zebra Browser Print - "Remote access not allowed"

Hello,

I have this model of Zebra: gk420T.

The printer is connected via USB to a PC, on this computer has been installed Zebra Browser Print.

Unfortunately when I try to reach the printer remotely I get: "Remote access not allowed".

I tried to reach the printer via php script and also directly through the browser with this url:

http://<IP-ADDRESS>:9100/

I've already edit the "settings.json" by adding the allowed host without success.

Can someone help me?
