I’ve created an Ionic 2 app and built it for Windows 10, and then installed the appx onto my Surface 3 tablet. This app is intended to access local network HTTP servers via IP address (specifically a couple of Raspberry Pi devices).
What I’ve discovered is that Windows Firewall absolutely refuses to let my app make any outbound connections. First I tried properly adding my app in the allowed list. No luck. Second, I tried disabling all firewall profiles. Still nothing. Lastly I went into the Windows services panel and totally shut off the Firewall service, and finally the app worked.
However, I’ve read that turning the firewall service off completely is a bad idea; it certainly is annoying because no apps will install while it’s turned off.
I’m completely at a loss as to what I need to do to get my app to work with the firewall. Does anyone have any ideas? Perhaps there’s something in the Windows app configuration files I need to set?
