OpenVPN: Mikrotik - server, OpenWRT - client, how to connect?

Question

openvpn

There is a working OpenVPN server on Mikrotik (x86 arch), I connect from any clients: Ubuntu (x64), Debian (ARM), Android 4.4.2 (ARM), Windows 7 (x64) but not with OpenWRT (MIPS, Barrier Breaker 14.07) , D-Link DIR-825 C1 rev.). When changing the platform, the config did not change, it works fine.
Config:
client
remote 127.0.0.1 1194
proto tcp
dev tap
persist-key
persist-tun
ca ca.crt
cert MikroTik_OpenVPN_Client.crt
key MikroTik_OpenVPN_Client.key
script-security 2 system
up /etc/openvpn/routes
log /var/log/openvpn. log
verb 5
auth-user-pass auth.cfg

Where could be the problem?

Answer 1

There is a source of problems: Mikrotik uses openssl 0.9.8 (2005), ubuntu 1.0.1f (2014), and openwrt 1.0.2 (2015). The network says that the new version of openssl does not have support for older versions, hence the problems.

Answer 2

The line
remote 127.0.0.1 1194
is obviously wrong.
This is what the log says:
