I recently began working on a small Node website on my computer, and it has been running fine for a few days on port 80. I am able to connect to localhost, 127.0.0.1, 192.168.1.2 (my network IP address) and my public IP address (I have port forwarded) I restarted my computer, ran the program from console with Admin permissions and now when I connect to 192.168.1.2, or my public IP address, Chrome gives me the error: "No webpage was found for the web address: http://192.168.1.2/" IISNode is an alternative, but I have had lots of trouble setting it up. Netstat indicates port 80 is not blocked, and I have removed the default website from IIS. Port 80 is open on YouGetSignal. Express is started on var server = app.listen(80, "0.0.0.0"); I have restarted my computer a few more times. All of my research has yielded nothing. What could be going on?
Using Command Prompt in Admin, is issued netstat -aon | find ":80" and there was a process using port 80. I then issued Taskkill /PID <YOUR PID> /F because the process didn't show on task manager. The issue was then resolved.

I created my App from this boilerplate
https://github.com/Bikranshu/express-react-boilerplate
Now I uploaded it to a live Linux server and Node server is running.
Screenshot of running server
But I am unable to access it through Browser with IP address of server.
http://ip_address:3000
After waiting long in browser it is showing timeout error.
Please guide me how can I access the node/react app from browser.
Server running at <ipaddress> is a local IP, are you in a different network than the server? If so, you should be typing https://<public ipaddress>:3000
UPDATE
Hosting services usually only forward port 80 (http) or 443 (https.) This means that your port 3000 is not allowed for public access. To fix your problem you need to change the listening port.
Check line 42 on
server/app.js change 'port' to "80" or check package.json and edit npm start to set port to 80
I have an app that is running on host: http://localhost:1111, when I try to access it through my server ip as follow: xxx.xx.xxx.xx:1111 it is not showing anything. When I run my app on my local pc it is running perfectly good
I tried to open ports, ping the ip with the port
Im running my node app with grunt on a DO droplet. I start the server
Running "connect:server" (connect) task
Waiting forever...
Started connect web server on http://localhost:3000
But when I navigate to my dropletIP:3000 I cannot see the app, I get:
This site can’t be reached
mydropletIP refused to connect.
Shouldn't my app be available? I don't have nginx or anything installed.
I was having similar problem but the solution was simple. Change from 'localhost' to '0.0.0.0' i.e
.listen(8080, '0.0.0.0');
And then to test your api just enter your static ip of droplet with port that you have entered i.e droplet-ip:8080
Check the particular port is opened or not ,using following command
sudo ufw status
If any Firewall enabled and any port is block means you can see that.
netstat -an | grep "LISTEN " ( List of listening port on server)
I need this info ,then only we can find a problem
The goal is to connect to my home computer from outside. The ISP blocks all the ports (and demands $$$ for business package with static ip address), so simple port forwarding on home router does not work.
I have used putty to tunnel a listening port to a remote server: R2221:###.###.###.###:2221 (to make things simpler, the test server is a simple ftp server running on my home windows machine) (the entire ip address has to be specified -- with OpenSSH 1.0 running on the linux box wildcard address results in refusal of connection) (GatewayPorts are set to on).
Netstat -a confirms that port 2221 on the linux box is open and listening. However, whenever I try to connect to that port, it simply hangs. Command line ftp client says "connected to ###.###.###.###" and that's it. Running netstat again shows dozens of opened connections to port 2221, all coming from my windows box (I tried using browser as well as command line ftp client).
Which step am I missing?
Tried with RDP, VNC and FTP -- all of them hang, all of them connect when connecting through my home network (or my home router).
EDIT The setup is as follows:
PC 1 (windows) has FTP service running on port 2221. It uses PuTTY to tunnel a listening port to PC 2 (linux). PC 2 does show listening port when running netstat. Connecting to port 2221 on PC 2 either form PC 2 or from PC 3 results in hanging.
EDIT 2 Aaaand it worked. Using 127.0.0.1 instead of the remote machine's ip address was what corrected it. Thanks a lot.
Are you sure your -R command is correct? From what you say I suppose the command should be R2221:127.0.0.1:2221. The -R ssh option in form of port:host:hostport does the following: it opens port port on the remote side and forwards the connection to that port to local address host:hostport, and this connection is made from the local machine.
To make your local machine (the one that is running ssh client, e.g. PuTTY) connect to your local FTP server running on the same machine, use 127.0.0.1 as an address.
It also explains why you see a strange behaviour: when you actually connect to xxx.xxx.xxx.xxx:2221, it forwards the connection to the same address xxx.xxx.xxx.xxx:2221 and you get some kind of a loop.
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
