OpenVpn client do not reconnect after longer period

[magik]

Hello everybody,
I have problem with one setting in client applications on Android IOS etc. I am looking for some options in settings to force client apps trying to reconnect infinite. For example I use Wi-Fi and when I go home from work and connect to another Wi-Fi after 15 minutes or hour, then openvpn app do not reconnect automatically. If i switch wifi fast, everything work well, switch between mobile broadband and wifi alsoworks well. I tested it on more phones and everytime it is same. I tried it found on internet, but did not found solution. So is there some option on client or server side in config to force infinite reconnect openvpn?
