SSH into multiple servers based on Domain HOST ACL

Hi,
What I’m trying to achieve here is using 1 Entry point for all of my servers using a private network.

1 server with Public IP access and then pointed multiple domains on it, after that use ACL to decide which backend to use.

Example Configurations:

frontend UK-1
bind *:77
option tcplog
mode tcp
  
tcp-request inspect-delay 60s
acl is_ssh payload(0,7) -m bin 5353482d322e30 # "SSH-2.0" in hex
tcp-request content accept if is_ssh

# Define hosts
acl l1_dom req.ssl_sni -i uk-ep-1.example.com
use_backend l1_ssh if l1_dom
  
acl i1_dom req.ssl_sni -i -i uk-ep-1.i1.example.com
use_backend i1_ssh if i1_dom

backend DefaultBackend
mode http
http-request deny deny_status 403

backend i1_ssh
mode tcp
timeout connect 3000
timeout server  7200000
option          httpchk
server          ssh 192.168.0.155:2905

backend l1_ssh
mode tcp
timeout connect 3000
timeout server  7200000
option          httpchk
server          ssh 192.168.0.167:2917

Unfortunately, this is not working.
