Transport Error on OpenVPN 1.0.7 build 199 on iOS 9.3.2

In case it might help: I am getting the same error message when trying to establish a connection to a QNAP box, whereas a connection to a Synology box seems to work just fine. Both machines have the latest software installed, but I haven't done any digging into the details of the two installations. If you need more information, just let me know.

Hi, i had the same problem. I have fix it.

Go to Iphone Settings-> OpenVPN

Turn on -> Force AES-CBC ciphersuites

This has worked for me.

@mcdbpas: Thanks a lot. That brought the openvpn-connections on my iOS and Android devices back to life.

It would be nice, if that kind of changes causing this kind of problems, would get confirmed before releasing new versions. Obviously iOS and Android devices were affected by this problem.

Is there any information why this option got changed at all? I could think of the following two reasons:
1. connection problems with other devices
2. less secure connection (description says something about legacy vpn servers)
