Is your mobile phone using cellular data? I guess from what you’re saying it is.

In that case, I don’t think this is possible, as your app is connecting to a mobile network and there is no routing of inbound data packets to the local server.

Previously, with the wifi dongle on the PC, everything would have been connected to the same wifi network. Had you tried leaving that network with your phone and connecting via a cellular data service then the same issue would have arisen.

If you used something like a Raspberry Pi you could set-up a stand-alone server, but once again there would be no external connectivity once your phone stops connecting to the wifi network.
