Hello,
I tested an openvpn with 2 openvpn servers. (physically different server)
And then i could access an openvpn using iphone without any error but 2 openvpn servers showed different behaviors.
openvpn SVR 1.
Sslvpn on iphone was disconnected when iphone went to sleep mode. if iphone wokes up from sleep mode, iphone was trying to access and then accessed successfully.

I tested with same mobile device using same version of opensslvpn app.
according to the log from OpenVPN SVR 1, it has a OS EVENT log like following.
2017-12-21 16:29:59 OS Event: SLEEP
2017-12-21 16:30:11 OS Event: WAKEUP
But, OpenVPN SVR2 doesn't have a log related to OS EVENT.
I thought that it was because different configuration, but i didn't find out different configuration in between 2 openvpn servers.
If it is possible, I want that openvpn on iphone keeps a sslvpn connection when it go to sleep mode.
But if it is impossible to keep the sslvpn connection when iphone go into sleep mode. i want to keep the sslvpn connection as long as possible.
Anyone can help me know why they have different behaviors in between two openvpns?
