Unable to connect to a listening tcp port 80, Iptables is not blocking it

I am trying to see if tcp port 80 is open on a debian 11 server. I logged into it using SSH and did curl -v telnet://localhost:80. It says connection refused. If I do the same with port 22, it shows that I am connected to SSH service. Machine doesn't have telnet or netstat installed locally. It has ss and nc The IP of the interface is 10.31.45.82 and the output of sudo ss -antp is: Proto State Recv-Q Send-Q Local Address:Port Peer Address:Port tcp LISTEN 0 32 10.31.45.82:80 0.0.0.0:* users:(("openvpn",pid=709,fd=7)) curl -v telnet://10.31.45.82:80 is showing connection refused. Same with nc 10.31.45.82 80 I am not sure what is blocking the port. IP tables input chain has policy ACCEPT so that's not blocking the port. Any ideas? I am confused as to why localhost port 80 is showing as refused. Can an external firewall block telnet on localhost? I used nc localhost 22 and it's connecting to SSH and it shows ESTAB in ss -antp. But nc localhost 80 is showing connection refused. sudo iptables-save -c output:
