OpenVPN Connect not working for certain server configuration (Android and iOS)

[CypZ]

Hello,

Since I think this is a bug in OpenVPN Connect, I publish here. I can't get my config to work with OpenVPN Connect (Android and iOS iPhone/iPad tested). OpenVPNGui for windows and some other OpenVPN Client on Android works well...

Is this still a problem with recent versions of Connect? Note that Connect for iOS v1.2.6 has been just released. May you test that and re-open this bug if the problem still persists?

Thanks!
