Jitsi Sever behind a HAPROXY Configuration

Hey Guys,

I want to Load Balence my Jitsi Server with a HAPROXY. I setup two Jitsi server each of the Server have two Videobridges. Both of the Server work perfect. After I setup my HAPROXY I searched for configurations but non of them worked right.
This my config:
frontend http_front
bind *:80
bind *:443 ssl crt /etc/ssl alpn h2,http/1.1
http-request redirect scheme https unless { ssl_fc }
http-response set-header Strict-Transport-Security max-age=63072000
log-format “client\ =\ %ci:%cp,\ server\ =\ %si:%sp%HU\ (%s),\ backend\ =\ %bi:%bp\ (%b),\ status\ =\ %ST”
default_backend be_jitsi

acl ACL_mydomain hdr(host) -i mydomain
use_backend be_jitsi if ACL_mydomain
default_backend be_error

backend be_jitsi
timeout connect 30s
timeout server 30s
option httpchk GET /
http-check expect status 200
balance roundrobin
mode http
option forwardfor
http-reuse safe
http-request set-header Room %[urlp(room)]
acl room_found urlp(room) -m found
stick-table type string len 128 size 2k expire 1d
stick on hdr(Room) if room_found
server Signalling1 IP:443 maxconn 100 check ssl verify none
server Signalling2 IP:443 maxconn 100 check ssl verify none

At the moment my config works but my balence is Roundrobin and this is not what I want, because the user dont get on the same Server.

Does anybody know a config that works? I know there some posts here but the configs didnt worked.

And please excuse me for my terrible english.
