sstpc - ubuntu - sspt client - error

I installed the sstp client in ubuntu and when I am trying to connect to the mikrotik sstp server I get the following error
**Error: HTTP handshake with server failed, (-1)
I can see the connection popping up in the firewall connections but nothing more than that.

If you have any experience with this tool or any other way to create an sstp connection to a mikrotik please share it.

For reference I used the following to install it:
add-apt-repository ppa:eivnaes/network-manager-sstp
apt-get update
apt-get install network-manager-sstp

Thank you

The first question is: do we debug only the ubuntu side or the whole setup because the ubuntu is the first client ever you try to connect to this particular SSTP server?

sstp is working fine…
other mikrotiks can connect
ubuntu can’t

I basically installed ovpn and it works but since we opened this discussion it would be handy to see if anyone made it work with sstp as well
