HAPROXY : Multiple Public Services on same IP, PORT but mode TCP and SSL/HTTPS

[Dead-Red]

Hello All,

I have this config :

OpnSense :     23.1.5_4

Theses subs works fine behind a public services with TYPE : SSL/HTTPS

sub1.domain1.com --> IP : A.A.A.A :443
sub2.domain1.com --> IP : A.A.A.A :443

I have this subdomain works fine (only if below public service is disabled) behind a public services with TYPE : tcp

sub1.domain2.com --> IP : A.A.A.A :443

But i can't enabled theses 2 public services  in same time.
The public service in tcp mode display :

503 Service Unavailable
No server is available to handle this request.

----------------------- Configs -------------------------

Can you tell me if it is possible to run a public service that shares the same IP/port but with 2 different modes?

If so, could one of you tell me where I'm going wrong? Because if we activate individually these public services everything works correctly.

Thanks in advance for your help

hi
afaik there is no complains frOm haproxy if there is multiple frontends bindings to the same sockest. but this misconfig is on admin. it "works" because of SO_REUSEPORT using.
