Hi, I faced an issue regarding the ufw ubuntu firewall rule in digital ocean, I already allow the port in in from anywhere but still I can not access to my application with public ip with the port that I allowed. How to allow the ufw firewall rule for my application in secure ways. Thank you. Event I try to disable the ufw from ubuntu, still I can not access my application through public IP address.
Rule: To Action From

Hi @jonhzono,
Have you figured out the issue? I’m running through the same problem. I tried:
Still no go. I get
curl: (7) Failed to connect to 104.***.**.160 port 443: Connection refusedwhen I’m on the same machine. But works from outside.Hello, @jonhzono
Could you also please make sure that your application is running/listening on the port as well? You can check this using netstat:
If UFW is disabled and you still can’t access your application then it might be something else that is preventing you from loading your application.
If you can see that the service is up and running on the specified port then you can check if the service is also visible from outside the droplet by using nmap:

Let me know how it goes.
