Can't change route table for outgoing SSTP-connection

Hi.

I have sstp-client:

/interface sstp-client
add add-default-route=no authentication=pap,chap,mschap1,mschap2 certificate=
none connect-to=x.x.x.x:443 dial-on-demand=no disabled=no http-proxy=
0.0.0.0:443 keepalive-timeout=60 max-mru=1500 max-mtu=1500 mrru=disabled
name=sstp-to-ask-hzde password=secret profile=default-encryption
user=user verify-server-address-from-certificate=yes
verify-server-certificate=no

I’m trying to change routing table for this sstp-connection.
I do following:

/ip firewall mangle
add action=mark-connection chain=output disabled=no dst-address=x.x.x.x
new-connection-mark=yota-conn passthrough=no port=443 protocol=tcp
add action=mark-routing chain=prerouting connection-mark=yota-conn disabled=
no new-routing-mark=yota-route passthrough=no

/ip route rule
add action=lookup-only-in-table disabled=no routing-mark=yota-route table=
yota

but SSTP client ignore this. Counters in /ip firewall mangle is growing, but the connection is still going through another gateway.

What I do wrong?
