We are running Haproxy and 3 nginx processes inside a single docker on the host network to access it from localhost. We have installed HaProxy version 2.6.6. 3 nginx servers are running behind it as backend servers. We are able to access them individually What is wrong with the haproxy configuration here? we are always getting the below error on curl (curl http://localhost:80) requests. Please suggest
<html><body><h1>503 Service Unavailable</h1>
