I configured the HaProxy properly and didn’t use the port 80. I ran netstat -ntlp command on all of the app servers and collected httpd default port number then used that port in the haproxy configuration file. I am requesting @Ayman team to check the issue.
Seems like you didn’t configure Haproxy to work on port 80 it was using 5000 port by default.
i think that might be the issue
