Description of Issue

Hi:

My roon core resides on my SB2 works fine. However, I can not connect my Roon remote on my iPhone 11 pro max to it. It keeps saysing “Looking for your Roon Core” forever…

I tried with my ipad same problem.
NOTE: iPhone and Roon core on the same network, subnet mask, et… On my SB2 I can ping my iPhone IP address normally.

Please help urgently!

Kind regards, Phong Nguyen.

I solved this already. Turned out that I just need to edit the firewall on my SB2 to allow for incoming and outgoing roon with public network, then my other Lenovo laptop and iPad can connect to my Roon Core just fine.
