My server's hosted at DigitalOcean (it's a droplet) and basically, I cannot access my NodeJS app via Internet, only server-side. It's running on port 9000, I've allowed traffic to the port via ufw and iptables, no luck. When I run curl || wget while SSH-ed to the server, I get a normal response as if everything's in order. But when I try to access the server from an another machine, I just get timed out because the server returns nothing. I've heard DigitalOcean sometimes disable connections to all ports except ssh,www and ssl, but I think I've successfully 'opened' them. Any suggestions?
This is what I get when I run netstat -tulp | grep LISTEN
Turns out my dashboard was all messed up when it comes to ports, which I forgot to check, of course, so opening them directly on the server gave no results whatsoever.

I'm trying to run a nodejs app on my VPS but for somereason I get a ERR_CONNECTION_TIMED_OUT error.
Here is my code:
const http = require('http');
const server = http.createServer((req, res) => {
res.end();
});
server.on('clientError', (err, socket) => {
socket.end('HTTP/1.1 400 Bad Request\r\n\r\n');
});
server.listen(8000);
when i cd to my directory and do
node index.js
, it gives me no error, but going to the browser and doing: mysite.com:8000 gives me nothing. The connections times out
EDIT:
when i do curl: enomshop.tk:8000, I get some feedback. Its like i can access from the within the VPS but no access publicly
This is the way you should go about resolving such issues
Check if the process is running
Run ps aux | grep <process> to check if your process is running
Check if the port is being used
Run sudo netstat -plant | grep <port> to check if port is listening or not and is it your process
Check if the service is responding locally
Run telnet 127.0.0.1 <port> and make sure you get a response. If you don't get a response then there are few possible issues you can look into
The process is not started the server listening
The process is not using the correct port
There is a firewall that is blocking the port. There is this for firewall-cmd, and this for ufw
Check if the service is responding externally
You can do telnet <external ip> <port>, if it doesn't work then there few things you should check below
Make sure your server is binding to 0.0.0.0 or <private ip> and not 127.0.0.1
Make sure the VPS server you are hosting on, has your <port> enabled for communication. This is different for each service provider
If you follow these steps, it would solve most common network issues in such cases
I was facing the same issue. To resolve that, just open up / allow the port from network security group (VPS) or Firewall to worldwide access.
And check telnet mysite.com port, it worked for me. Kindly let me know if you still face any issue, I will try to help further.
You will need to open up the 8000 port on your VPS or redirect the traffic from any open port on VPS to 8000
Hi guys im newbie in vps... I've bought an ovh not managed vps . I like to face problems... But I don't find any documents to these one. Is simple like I said I want to run a nodejs app in centos vps environment but I have enabled plesk.. and I saw in console running the app with the trace but I try to open website with the port and doesn't find anything.
http://vps406315.ovh.net
Thx for all guys
-----------------EDIT-------------------
I'm going to explain better,sorry for previous post.
There is no error, in my console all is ok. Like I said i have an CentOS VPS. Steps that I did:
Connect with PUTTY
Go to folder where is the NodeJS project.
I set the port to 8080
Write node index.js
The app is running and writing the right trace.
I use chrome to check the ip, and show me the default plesk page.
I use wget to check it, and with only http://92.222.71.137/. I attach
an screenshot
I tried to use with the port 8080 with the chrome and wget in putty,
and the response was the same.
In the other hand if I use http://92.222.71.137:8080/login with putty
download the right login.html, and the nodejs app write a trace
indicate me that someone connect to that page. But if I access with
chrome is not working.
Now I would like no know how to make access frome Chrome.
Thx 4 all and sorry for my newbie knowledge
You should give some other details on the configuration or eventual errors you get (both on the browser and the VPS) and how you run the node app (behind a web server, for example)
If you are not running you node app behind a web server, are the node app listening on the correct interface ? 127.0.0.1 and 92.222.71.137 (your site external address) are not the same.
On your VPS you can try to call the node app from the VPS itself using wget or cURL and looking for what happen in the app trace.
Finally it was easy... only i had to open a port to use with TCP, using
iptables -I INPUT -p tcp --dport 8856 --syn -j ACCEPT –
I am running node server running react application.server is run by webpack. Server is running on 10.121.45.23:3005. I tried opening the application on other machine but page displays connection timed out. I have tried following things to resolve the issue, but nothing helped.
ping 10.121.45.23 from another machine. It is successful.
On server, netstat -ano. I am able to see 10.121.45.23:3005 listening. No loopback address was there as mentioned in many answers on Stack Overflow.
On another machine,telnet 10.121.45.23 3005. It fails and say cannot connect on port 3005. Telnet to some other port on which java is running, is successful. It fails only for node.js server.
So my problems are:
telnet is not working to that port.
Not able to open application on other machine's browser.
Am I missing any checks?
Sounds like you've tested quiet a bit. Have you tried another port, just in case there's a firewall or something?
Also, try explicitly telling webpack to listen on the all-hosts address 0.0.0.0
webpack-dev-server --port 9000 --host 0.0.0.0
I'm trying to run a node web app (built with meteor) on a Centos7 server running EasyApache4 with WHM cPanel. I'm trying to run it on a subdomain off of one of our main websites on port 8080.
When going to the subdomain on port 8080, the connection just times out, but can see the html when using curl to access it.
Does anyone have any ideas why it won't work through the browser, and also how I can get it to look like it's running straight from the subdomain instead of having to go directly to the port.
EDIT
Below is the curl we are using to view the html
curl http://subdomain.site.com:8080
Doing that brings back the html no problems
Had the same problem today. I am using Memset Centos7 server with WHM/CPanel, running EasyApache 4.
After trying everything I could think of, I realised that I had a basic firewall setup, which closed all ports that were not listed. After adding port 8080, it worked.
Used this:
sudo iptables -I INPUT 1 -i + -p tcp --dport 8080 -j ACCEPT
I am not 100% certain how secure this is, as I am still researching.
I have a VPS with node.js installed, I already uploaded a basic example to test it on the server, so I tried doing this:
I access by SSH, navigate to my project folder and run
node app.js
I get this message
Express server listening on port 8080
I thought i could see my app here
example.com:8080 or server.example:8080... but nothing. Then I tried with the info from os.networkInterfaces(); and os.host(); and still nothing happen
could you help me out? as you can see I am a total noob on node.js. What I'm doing wrong? or what should I do before running my app? Something related to DNS's? i have no idea
How do you ssh to your host? with ip or name? Is it something like:
ssh root#example.com
if so then at least you know your DNS is ok.
Once on the server do a
netstat -a
if you find *:8080 then your server is listening in the default ip. If you see something like 12.23.45.67:8080 then this number is the ip your server is listening.
ifconfig
will give you the servers ip. This should be the same as the ip of example.com. If not then maybe there is some router/firewall in front of your server and you have to configure that to allow port 8080 to reach your server.
if someone ever has the same problem this is how i solved on CentOS:
Open this file
/ Etc / csf / csf.conf
Add the required port
Allow incoming TCP ports
TCP_IN = "20,21,22,25,53,80,110,143,443,465,587,993,995,26"
Allow outgoing TCP ports
TCP_OUT = "20,21,22,25,37,43,53,80,110,113,443,587,873"
Restart
# # Csf-r
