Can't import .ovpn profile on Android and iOS with 16384b RSA Key.

With Tunnelblick on Mac works perfectly,but on mobile device got an error.
Here is log example:

08:15:35.630 -- ----- OpenVPN Start -----

Try on OpenVPN Connect 3.0.5(1816) on Android and OpenVPN 3.0.2(894) on iOS

This is probably a limitation of the mbed TLS used in those apps. And 16k RSA keys are not really common.

I am just closing this as "works as indented"

Yes, as i understand,it's limitation of mbed TLS. Can you help me, where i can find source code for OpenVPN Connect for android? mbed TLS support tell me,that i need to change value in config file,but i didn't see it in app folder, so maybe it changes in source.

Thanks!

OpenVPN Connect for Android is not a Open Source app. You can use OpenVPN for Android instead, if you need an open source app.
