Running NGINXon Alibaba ECS is not reachable from the web

On Alibaba Cloud ECS instance I have NGINX working normally, I can ping it from my terminal but I can't access my site from the browser.

nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

service nginx status

It's problem with your Firewall, try to allow port 80 / 443

sudo ufw allow 80/tcp
sudo ufw allow 443/tcp

And check the port is listen to 0.0.0.0 with

sudo netstat -tunalp | grep 80
sudo netstat -tunalp | grep 443

If it's not solve your problem with your internal security group on alibaba Console

  • Go to ECS Console.
  • in tab Network & Security, choose Security Groups

And make sure you have allow port 80 / 443 or if you want allow all port int security Groups like this

Did you selected Assign Public IP Address when you created ECS instance? It sounds to me like it does not have NatPublicIP address assigned during creation process of ECS.

Try to open ports:

sudo ufw allow 80/tcp
sudo ufw allow 443/tcp

Then try further to inspect ports:

sudo lsof -P -n -i :80 -i :443 | grep LISTEN

Check the status of local host:

curl -i http://127.0.0.1/nginx_status

Also try to restart server:

sudo service nginx restart
sudo service nginx reload

If this does not help, try to go in debug mode and trace common errors.

If this does not help, go from the start with instance and nginx installation.

Hope this would give you idea about what step was missed.
