"Unable to obtain owned devices" and CertPathValidatorException

BLE Beacons
1

I’m using ConfigurableDevicesScanner.

ConfigurableDevicesScanner devicesScanner = new ConfigurableDevicesScanner(this);
devicesScanner.setOwnDevicesFiltering(true);
devicesScanner.setDeviceTypes(DeviceType.LOCATION_BEACON);
devicesScanner.setScanPeriodMillis(1000);

While the app scans, I always get an exception and no devices are found.
Strange is, if I using mobile data connection it seems to run very well, but if I using Wi-Fi connection, I get this:

Are you sure you’re fully authenticated with your WiFi network? It looks like the router could be redirecting the connection to a login page or something like that.

problem solved: our network administrator has changed the firewall settings :slight_smile:
