Access plugin over wifi

Hi. I installed Signalk on my windows plotter. Also I downloaded the autopilot plugin and I can access ist via localhost. The windows machine is a client in a wifi network (opened by the multiplexer) and has the ip 192.168.4.3. Now I want to access the plugin from my android phone, which is a client in the network too. Does that work, and if so, what is the correct address to use?
