Can't connect to a WiFi network when connected to a VPN #310

johnmaguire commented 1 year ago

I'm using wifi_iot. If conected the Nebula VPN app (it's a mesh overlay networking VPN, similar to Tailscale - it is only used to route some private IP addresses, it is not a VPN that connects me to the WAN) I'm unable to connect to a network using wifi_iot.

If I am connected to the VPN then network.connect() fails. This is the only thing I saw in logcat that looked interesting:

I'm using a Pixel 6 on Android 13.

I haven't gone through these (connect with VPN enabled) use-case.

I suspect that VPN needs to be configured with WifiNetworkSuggestion.Builder and WifiNetworkSpecifier.Builder. I am busy with other work these days, urge you to look into this yourself. If you come up with something - we can decide how to integrate it into the plugin.
