Unable to connect to custom port on Amazon EC2 instance

Question

I'm unable to connect to my Ubuntu EC2 instance on port 5000 where my app is running.

I have security group rule in place to allow 80 and 5000
Ubuntu firewall is disabled -sudo ufw disable and I tried enabling it and added port 5000 as well
I'm able to ping the server
But accessing port 5000 does not work

did you try `curl localhost:5000` inside machine? is it accessible on localhost? — Adiii, Dec 05 '19 at 14:41
which server you are running? is it bind to localhost? is nodejs based application or which framework? — Adiii, Dec 05 '19 at 14:59
I added this line .UseUrls("https://*:5001/"); Still not able to access from outside. port 5001 is allowed in the security config. — Tra, Dec 05 '19 at 15:48
Sorry. The changes I made was not updated on EC2 properly. .UseUrls(new string[]{"http://*:5000/","https://*:5001/"}); with this change, Im able access it via http://serverip/5000 But still 5001 not working. may be a security certificate issue. — Tra, Dec 05 '19 at 16:29

If working on localhost, and SG also allow the traffic then it Seems like your server is bind with localhost, update to server configuration to listen 0.0.0.0.

Add this in the configuration.

UseUrls("http://0.0.0.0:5001/")

How do I get the kestrel web server to listen to non-localhost requests?

Is there a reason you're using port `5001` instead of port `5000`? – iggy12345 Jan 30 '23 at 20:34
nope, it was just an example, the port should be same as the one on which server listening – Adiii Jan 31 '23 at 17:37
