Android - OpenVPN - QNCM onlineState

ekkescorner

are there any known problems with OpenVPN ?

some of my customers are using BlackBerry UEM where Android devices are connected to server via VPN
all works well on Android and iOS

On Android I’m listening to QNCM onlineStateChanged(bool) SIGNAL
On iOS I’m listening to ReachabilityListener.mm

now got a report from one customer using OpenVPN on Android where online state not always correct if switching between WIFI and mobile network:
infos from customer - not verified by me what happens in detail under the hood:

WIFI ON, VPN ON: start App: ONLINE
switching WIFI OFF, device changed to LTE (mobile), VPN ON, App Status: ONLINE
switching back to WIFI ON, device changed to WIFI, VPN ON, App Status: OFFLINE and doesn’t come back to ONLINE

any ideas or experiences ?
