Description
I have a Node server and React App running on my notebook Ubuntu 18.04.
Notebook ip is 10.0.0.101
I tried to connect my desktop to this server on the same network
Desktop ip is 10.0.0.100
Node is running on PORT=3333
React is running on PORT=3000
I can ping my notebook from my desktop but when I try to connect to node using Insomnia or to http://10.0.0.101:3000 from my desktop I cannot reach.
Errors
When try to connect to backend with Insomnia
Error: Couldn't connect to server
When try to connect to app on 10.0.0.101:3000
ERR_CONNECTION_TIMED_OUT
What I've done
I already changed the node listen and specified the port and the ip but it didn't work.
I tried to use my phone as router and connect from my phone to react on my notebook and also didn't work.
I've tried so many things since I can't remember them all.
I'm also creating a react-native app and when I try to connect to my mobile using Expo, it just works using tunnel, but cannot get data from the backend.
Please save me.
Thanks
After making many failed attempts, I realized that the problem was in my notebook.
I checked my firewall and it was disabled and still cannot get acess to my notebook on LAN. But finally I discovered what have to be done
Solution
You have to open the specific port for TCP traffic
Ubuntu:
sudo ufw allow <PORT-NUMBER>/tcp
or for Red Hat Enterprise
firewall-cmd --add-port <PORT-NUMER>/tcp

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 –
An overview of my setup:
A socket.io/node server is being hosted/ran on a computer in my local network.
An Ionic app is attempting to connect to the socket.io/node server to send/receive messages.
If I run the app in the browser with 'ionic serve', I am able to connect to the socket.io/node server successfully.
If I run the app in the emulator or on my device, I am only able to connect to the socket.io/node server if I add the -l (livereload) flag (ionic run android -l).
Originally, I hosted the node server on a heroku instance. I had no troubles connecting with this setup from browser, phone, or emulator. I had to switch to running the node server on a local computer so I have access to a local database.
Any ideas what is going on?
I fixed it by adding 'http://' to the beginning of the connection string.
Not sure why Ionic's livereload enabled me to connect without the 'http'
I've installed cloud 9 Ubuntu 14.04 (Desktop), and executed it by typing:
node [cloud9folder]/server.js -p 8080 -a :
I was able to connect to it by typing localhost:8080 (On the same computer that is running cloud 9) but when I went on another computer on the same network, I was unable to connect by typing [ip address of the computer running cloud9]:8080 into the browser. The browser returned: "Webpage not available (ERR_CONNECTION_REFUSED)."
I know the server computer is working, I was able to access it's apache2 website but for some reason it is unable to connect to cloud 9.
How do I fix this?
also add -l 0.0.0.0 by default server is listening on 127.0.0.1 which is not public
I recently setup an Ubuntu 12.04 LTS server running nginx, and I could connect to it via its IP address. However, after restarting my computer I can no longer connect to the server in any browser but I can connect via SSH through puTTy. No clue what's going on and ifconfig shows that the IP address has not changed and I changed no settings on the server. How can I fix this?
This picture shows the chrome window response when I try to access the server, the ifconfig from the server (top right), the network settings on the VM (bottom left), and the location settings for /etc/nginx/sites-available/www.
server settings
I have tried restarting, doing an nginx reload, and a full computer restart. Nothing has worked so far. All help is greatly appreciated!
First make sure that the service is working using sudo service nginx status
If it's not running try starting it manually sudo service nginx start
If it fails to start, you can check the error log in /var/log/nginx/error.log or any other error log defined in the server config.
