Cannot add HUE Bridge to Hue essentials - Wrong IP address?

Hello all,

I have been trying to add my hue bridge that is not on the same network, to my hue essentials, and when i do a manual hue bridge add i keep getting an invalid ip address error.
Both networks are routed between them, and no firewall is present.

The ip addr that i am adding is 172.16.15.2, port 80

What am i missing? Is there a different format that the app is expecting me to input for the ip?
Also my hue essentials is running on an android tv - sony bravia

Thanks for your help

To make sure that your IP address is correct, please open the IP address in a web browser. If that device can access your Hue bridge, it should show a page about Philips Hue. Then Hue Essentials should work as well with that IP address. What happens when you open the IP in a web browser?

The format you mentioned is correct.

Are you able to control your Hue bridge from your phone when it is on the same network as your Android TV?

Hello Thomas,

The IP opens ok, with the HUE info:

However when i put the IP in the app (android tv), it says invalid IP.
And yes, i can control the HUE bridge form my phone, on the same network as my TV.
