[SOLVED] Port 8080 not working on EC2 instance gunicorn

Port 8080 not working on EC2 instance gunicorn

I'm running airflow with a gunicorn server on port 8080 on red hat EC2 . I can't connect to it externally and get Timeout exceeded error

Within the EC2, I can wget ip-server:8080 and when opening index.html, I do see airflow running.

I do see server listening on address 0.0.0.0:8080 netstat

Here are my inbounds rules Inbound rules

When I run sudo iptables -L -v -n | more, I don't see any rules iptables

VpC subnet is like this Subnet ec2

ACL rules ACL rules

Using top, I see that the server is not overloaded.

All of the above seems Ok, what did I miss ? Thanks

Solution

Turns out the firewall was running sudo systemctl status firewalld. I stopped it using sudo systemctl stop firewalld and it worked ! I also ran sudo systemtcl disable firewall to make sure it does not reactivate when laucnhing instance.
