Not able to access port 80 on my Ubuntu 22.04 Azure VM

I have added port 80 HTTP and port 443 HTTPS in my inbound network rules, but when I try to open a connection on port 80 it says Permission denied or when I try to do curl localhost:80 on my VM it says curl: (7) Failed to connect to localhost port 80 after 0 ms: Connection refused.

I have tried everything like removing the port from inbound rules and restarting the VM still it doesn't help. Also my UFW is also inactive so it's not a problem from that also. Add when I use netstat to see if anything is running on port 80 it says Port 80 is not available.

    You mis-intpret the messages.

    If the port would be blocked by Firewall, then you get not connectio at all and after 30 seconds you get a timeout error.

    But you get "permission denied" and that means, the conection was successful, but you as user don't permissions to access the web server.
