Failed to connect to /192.168.4.1 (port 80) from /[EXTERNAL IP] (port X) after 5000ms

I'm trying to provision with SoftAP, letting this library establish the WiFi connection as well (using device.connectWiFiDevice(name, password). Most of the time I'm getting the above error. Rarely it succeeds, and device.scanNetworks(...) also works, but the provisioning always fails with this error.

The problem most probably is that it tries to reach the SoftAP endpoint from the external address as suggested by the error message.

Any ideas how to force it to connect from the WiFi interface?

Hi @szekelyisz ,

As per description, app is able to connect with device and also able to display scanned networks.

After sending Wi-Fi credential to device, do you see any error in phone app or on device console ?

Hi @khushbushah2302 thanks for your help!

It seems like when I use the default method connectWiFiDevice() after manually connecting to the wifi network, it seems to work (for a minute or so).

However, if I use connectWiFiDevice(name, password), it fails with the above error all the time. It looks like if connectivityManager.bindProcessToNetwork(network); didn't do its job, and the library tries to connect to the device through the cellular interface. Any ideas why this would happen?

I'm in API level 28 (P), so no WifiNetworkSpecifier.
