Hi Guys,

I have some strange error coming from my haproxy.cfg not sure what happened with my mac…i scanned all the ports nothing is listening…

only four digit bind ports only working inside my haproxy.cfg file, no two digit and three digit ports are working…I don’t know what happened could you please any one help me to solve this?

here is my haproxy.cfg in my local

**working haproxy.cfg:**
