I'm using websockets on my php-apache website, running on ubuntu. That worked well, until I added a SSL certificate. The certificate was generated using certbot from Let's Encrypt.
Now when I use
var websocket = WebSocket("wss://my_domain:4950/");
Chrome responds with this error : "WebSocket connection to 'wss://my_domain:4950/' failed: WebSocket opening handshake timed out"
I found some answers that I had to add another certificate for websockets, but I'm lost...

I have been developing a live chat that uses a websocket connection. It works fine on my localhost and on http servers. However, I am trying to get it working on a secure GoDaddy server with Deluxe Linux Hosting.
While the client is trying to open a websocket connection from javascript, it eventually responds with "WebSocket connection to 'wss://jhaubrich.com/new.projecthandle.io/Demo/include/projectChat/php-socket.php?username=Justin' failed: Error during WebSocket handshake: Unexpected response code: 504"
A 504 Gateway Timeout Error indicates an issue with the gateway or proxy server.
If I try to open the connection again without killing the PID for the lsphp, the error written to error_log by the php-socket.php file reads "PHP Warning: socket_bind(): unable to bind address [98]: Address already in use in /home/fq2cvob2t06k/public_html/new.projecthandle.io/Demo/include/projectChat/php-socket.php on line 12"
For the socket_bind() in php-socket.php I am using port 8090.
I have tried changing ports. I have tried adding 'websocket' to the end of the url in the websocket js.
//my js to initiate the websocket
var websocket = new WebSocket("ws://jhaubrich.com/new.projecthandle.io/Demo/include/projectChat/php-socket.php?username=" + userName + "" );
I expected a websocket connection to be made.
Instead I get this error : "WebSocket connection to 'wss://jhaubrich.com/new.projecthandle.io/Demo/include/projectChat/php-socket.php?username=Justin' failed: Error during WebSocket handshake: Unexpected response code: 504"
I came to the realization that I am use a shared hosting environment. I need to purchase a Virtual Private Server where I will have root privileges. Then I will be able to use WebSockets...
I have used websocket: https://github.com/kishor10d/CodeIgniter-Ratchet-Websocket
I have implemented websocket on a site. It is working great on localhost but when I uploaded files, it doesn't work. First there was confusion regarding the port I am using which is 2000. Now after contacting Inmotion's support they told me that 2000 is live and there are no firewall issues.
But I get this error when I reload the page:
WebSocket connection to 'ws://127.0.0.1:2000/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
According to their support there is no service listing to this port.
I have used CodeIgniter, Javascript
If you're calling the localhost (127.0.0.1) from the client app, you're calling your own computer, once you have the backend running on a remote server, you have to use the server's domain name or IP address - I'd suppose your web/server hosting service (Inmotion) assigned you the latter.
I am new to WebRTC and WebSockets and was following this tutorial to create a WebRTC demo project, but I am unable to create a WebSocket connection. I have followed the same steps as mentioned in the project.
His project is running on port 8080 and he mentioned ws://localhost:9090. My project is running on port 8081, but I copied his URL ws://localhost:9090 because I didn't know the significance of 9090 and I received this error and my server is node.js. i changed local host to 8081 as well but then i am getting hand shake error.
WebSocket connection to 'ws://localhost:9090/' failed: Error in
connection establishment: net::ERR_CONNECTION_REFUSED.
Chrome doesn't allow unsecure websocket (ws) connections to localhost (only wss, so you should setup a TLS certificate for your local web/websocket server).
However the same should work fine with Firefox.
You need to use ws://yourIp:9090/, where yourIP is like 192.168.?.?.
Usually WebRTC requires a secure connection (that is https).
The error you have got is due to TLS/SSL certificates occupied, may be they are not properly configured in your project.
Provide a valid TLS/SSL certificate and also configure it correctly in project, then it will work without the above error.
try to change the port to 8080
const ws = new WebSocket('ws://localhost:8080/chat')
I guess this is a generic websocket issue.
Change the url to a dynamic name using the built-in location.host variable and change the protocol to secure websocket wss if you have set-up the TLS:
const ws = new WebSocket("wss://" + location.host + "/")
Port 9090 is used by reactotron. Probably you are using it in your project and your app cannot connect with reactotron because it is closed. Just open reactotron and the error will disappear.
also you could easily change the mappings of IP addresses to host names,
on windows go to C:\Windows\System32\drivers\etc\hosts and uncomment this line
127.0.0.1 localhost
save and restart.
WebSocket connection to 'ws://localhost:8080/' failed
Must ensure server file is running
I git this above problem
maybe you forgot to start websocket server, check it again, with configuration in my project, run:
php artisan websocket:init
I have purchased a certificate and installed in my node.js website.But the https at the browser shows green and is OK.Now, I am trying to establish a socket connection using wss, but it failed.
The error at the Javascript client side is like this.
WebSocket connection to 'wss://securedsitedotcom:3003/call' failed:
WebSocket opening handshake was canceled
Please help!
Code at client side (Javascript)
var ws = new WebSocket('wss://securedsitedotcom:3003/call');
Code at server side (node.js)
https = require('https');
var server = https.createServer({
key: fs.readFileSync(config.certKeyPath),
cert: fs.readFileSync(config.certCrt),
requestCert: true,
rejectUnauthorized: false
},app);
server.listen(port);
var wss = new ws.Server({
server: server,
path: '/call'
});
Error at the browser console :
WebSocket connection to 'wss://securedsitedotcom:3003/call' failed:
WebSocket opening handshake was canceled
Recent work with Chrome has revealed that if a page is served as https on Chrome, websockets must use wss. And if wss must be used, port 443 must be used (and to boot not any other secure port and so far I have not seen any way to change the port), which may be your problem since your port looks like 3003 above.
Right now I am trying to get my IT group to patch/upgrade Apache on that server so mod_proxy_wstunnel can be used to make Apache listening on 443 a reverse proxy and pass all wss traffic through to my websocket server.
Hope this helps.
I ran into a similar issue, but I was using a Self Signed Certificate. You mentioned that you bought a Certificate. I guest it is signed by the certificate authority.
Otherwise, like in my case, non-validated certificate can cause an "opening handshake was cancelled" error. A validated certificate is either validated by a third party (Certificate Authority, ie VeriSign) or explicitly authorized by the client.
In my case, VeriSign didn't sign my certificate (self signed), so I had to explicitly authorized it. To do so, I simply need to visit the https URL with the browser (in your case "https://securedsitedotcom:3003/call"). Then a "warning unauthorized host" appear. You need to authorize the exception and than you can make your WSS connection.
Your server can use any port, it is not bound to 443. 443 is the default port for https but any port can be explicitly specified like you've done.
I hope it helps someone.
I am hosting my app with Heroku and using websockets. When the browser sends a request the connection fails due to this error message:
Firefox can't establish a connection to the server at wss://shrouded-dawn-5557.herokuapp.com/ws
In my javascript file I create a new websocket object as:
ws = new WebSocket("ws://"+ location.host +"/ws");
Why is this not making the connection to the server.
Thanks
Solved this by enabling websockets in Heroku:
heroku labs:enable websockets -a myapp
