openvpn iOS tls failed

RouterOS General
1

Something changed since routeros v6.9. Now is not possible connect to mikrotik openvpn from IOS (iPhone) openvpn client (“disconnected ” error).
No problems detected connecting from viscosity (osx) or openvpn (linux terminal).
I have tried different ciphers and other configurations, but no success.
Tested routeros versions:
6.7 working
6.9 no
6.10 no
6.11 no
6.12 no
6.13 no
6.14 no
6.15 no

ROS OpenVPN Client with Linux OpenVPN server
OpenVPN Server error: TLS failed

It is exactly the same problem. With version 6.7 works, but the last build 6.16 does not work.

That may be happening?

It’s not only ios. I can’t connect anymore from windows GUI with a config that was operational before.

I found solution and now iOS openvpn client v. (1.0.4 build 140) connects to mikrotik routeros v 6.18.
IOS settings->openvpn->advanced settings->Force AES-CBC ciphersuites (disabled this option).
