[stunnel-users] Tunnelblick over stunnel - connects but does not work

Hi!

As OpenVPN seems to become banned in increasing number of countries, I had
to look for a way to foil DPI. Wrapping OpenVPN traffic into stunnel
SSL-secured connection seems promising but... On Windows machine it really
works just fine. But on macOS it connects, but then no surfing or other
Internet application works whatsoever. Looks like DNS problem but may be
it's different...

Moreover, in 40 secs or so Tunnelblick disconnects with message "2017-11-10
00:08:54 *Tunnelblick: After 30.0 seconds, gave up trying to fetch IP
address information using the ipInfo host's name after connecting.
2017-11-10 00:09:30 *Tunnelblick: After 30.0 seconds, gave up trying to
fetch IP address information using the ipInfo host's IP address after
connecting". Then it tries to connect again but never succeeds and cycles
forever.

Please find stunnel config and Tunnelblik full log below. Would appreciate
any help!
