Node.js server is running - why is the page not opening in the browser?

Question

Node.js

VPS: CentOS 6.6_x64
Installed Node.JS v.10.35
The web server script is in the file var/www/server.js
1. By command "node var/www/server.js" the server starts.
2. I open a browser, enter http://<my IP address>:8888
I did several actions on recommendations from the network, including -A INPUT -m state --state NEW -m tcp -p tcp --dport 8888 - j ACCEPT, did not help.
I understand that you need to open the port.
Tell me please!

Perhaps, after adding the rule to iptables, you did not save the table through service ip6tables saveand reloaded the basin. To check if there is a problem at least in it, turn it off for a while through service ip6tables stopcheck it in the browser and then turn it on through service ip6tables startand you can completely remove the firewall from the actupload through chkconfig ip6tables off, and return it through chkconfig ip6tables on. Try the following rule:

iptables -A INPUT -p tcp -m tcp --dport 8888 -j ACCEPT

But you also need to check whether the node server binds to the same IP (hostname) through the server.listen(port, [ip]). If you put IP "0.0.0.0", then it will sit on all interfaces. If all this does not help, then you need to check the firewall at the data center / hosting, perhaps there is a control panel in which you can forward ports to the outside world.
