I am mounting an ssl certificate in load balancer, install haproxy and when starting it I get this error:

If the file you paste is exactly the one use to satrt the server it seems normal not to start.

The lines global, default, frontend and backend are commented so the it can’t pass the config check.

Otherwise, If you have your config file , you can try a manual config check. It can give a hint about the issue :

haproxy -c -f <haproxy config file>
