I am new to HAPROXY DONT KNOW WHAT TO DO

Help!
1

I have haproxy installed and tested but config is where im lost

My haproxy server does not have a cert on it I was just forwarding port 80 and 443 to it

My backend servers all have letsencrypt already installed and have certs are on them but I recently dropped to one public staic ip and I need to configue to get to domain1, domain2 or domain3

And get there by either http or https request, this is all running in ESXI with different webservers running on different local ip addresses different domains and my main webser hosts 2 domains

What is the best way to go about this?

This is what I have BUT don"t work
