Im trying to connect from a client using socket.io :
<script src="https://cdn.socket.io/socket.io-1.3.5.js"></script>
<script>
var socket = io.connect('http://127.0.0.1:8000');
</script>
to a server running websockify to translate websocket traffic to normal tcp, im running it using the latest releases and :
./run 8000 :5000
but this error ocurrs:
WebSocket server settings:
- Listen on :8000
- Flash security policy server
- No SSL/TLS support (no cert file)
- proxying from :8000 to :5000
127.0.0.1 - - [30/Nov/2015 21:23:46] code 405, message Method Not Allowed
from what i have read this happens if you send a POST request to a server that doesnt allow it, is this whats causing this error? is there any way to configure websockify to accept such request?

I'm a beginner in Rust and WebSockets and I'm trying to deploy on Heroku a little chat backend I wrote (everything works on localhost). The build went well and I can see the app is running, and I'm now trying to connect to the WebSocket from a local HTML/Javascript frontend, but it is not working.
Here is my code creating the WebSocket on my rust server on Heroku (using the tungstenite WebSocket crate):
async fn main() -> Result<(), IoError> {
let port = env::var("PORT").unwrap_or_else(|_| "8080".to_string());
let addr = format!("0.0.0.0:{}", port);
// Create the event loop and TCP listener we'll accept connections on.
let try_socket = TcpListener::bind(&addr).await;
let listener = try_socket.expect("Failed to bind");
println!("Listening on: {}", addr);
and here is the code in my Javascript file that tries to connect to that WebSocket:
var ws = new WebSocket("wss://https://myappname.herokuapp.com/");
My web client gets the following error in the console:
WebSocket connection to 'wss://https//rocky-wave-51234.herokuapp.com/' failed
I searched to find the answer to my issue but unfortunately didn't find a fix so far. I've found hints that I might have to create an HTTP server first in my backend and then upgrade it to a WebSocket, but I can't find a resource on how to do that and don't even know if this is in fact the answer to my problem. Help would be greatly appreciated, thanks!
I think your mistake is the URL you use:
"wss://https://myappname.herokuapp.com/"
A URL usually starts with <protocol>://. The relevant protocols here are:
http - unencrypted hypertext
https - encrypted hypertext
ws - unencrypted websocket
wss - encrypted websocket
So if your URL is an encrypted websocket, it should start only with wss://, a connection cannot have multiple protocols at once:
"wss://myappname.herokuapp.com/"
I have build a Go server using Echo framework, i get TLS certificades and a domain name, but when i try a request i get the message "Client sent an HTTP request to an HTTPS server." and when i try acces the server from the IP address of the EC2 using the port 443, it says that the connection is not secure:
And when i change the server to the port 80 to acces through the domain name, i get the following error:
I'm starting the server using the StartTLS func
e.Logger.Fatal(e.StartTLS(":80", "/etc/letsencrypt/live/anltcsprod.enrtt.com/fullchain.pem", "/etc/letsencrypt/live/anltcsprod.enrtt.com/privkey.pem"))
Is it something wrong with my domain or certificade?
Port 80, by default, communicates over HTTP. 443 is reserved for HTTPS traffic. Assuming nothing else is wrong, you should be able to simply change your e.StartTLS() to this:
e.Logger.Fatal(e.StartTLS(":443", "/etc/letsencrypt/live/anltcsprod.enrtt.com/fullchain.pem", "/etc/letsencrypt/live/anltcsprod.enrtt.com/privkey.pem"))
For example localhost:4000
Instead use https://localhost:4000
I am trying to deploy my laravel project with websockets built on Beyond Code's package.
My server is on AWS and i'm using WHM.
on the cPanel's terminal i'm running the line php artisan websockets:serve
and i get the result Starting the WebSocket server on port 6001...
when i'm loading the page with the websocket's connection sometimes i get the error failed: Error during WebSocket handshake: Unexpected response code: 200
and sometimes i get the error failed: WebSocket is closed before the connection is established.
On AWS EC2's Security Groups i allowed the Custom TCP port 6001 and 6002
Any suggestions to fix it?
Maybe a good deployment tutorial for Laravel WebSockets?
I'm looking for answers all over the internet and i get nothing useful.
I have finished http protocol via the socket class according to rfc2616 protocol, but how to connect https protocol and send data to server using the socket class?
When i connected https server https://www.example.com, I always get 404 error. The following is the socket command that to send to server https://www.example.com/
GET / HTTP/1.1 Host: www.example.com
the default always use http protocol
I found connected to https server need to use a connect command instead of the Get command and a client certificate. for example:
CONNECT login.example.com:443 HTTP/1.0
Major Version: 3
Minor Version: 1
......
I will try to use the connect command. Thanks for your replies.
==================================================
OK,i have solved my problem ，use the SLStream class.
NetworkStream networkStream=new NetWorkStream(socket)
var stream=New SslStream(networkStream)
.......
Now, will can read stream and write stream, until finished.
First of all, sorry for my bad English : )
My Java application (multiplayer game server) uses this package to communicate with a web application in client's browser using websockets: https://github.com/TooTallNate/Java-WebSocket
I've encountered a problem running my application: only I can connect to the websocket server, clients on other hosts can't do so. In browser I estabilish connection as usual, address here is certainly correct:
new WebSocket("ws://"+serverIp+":8787");
When I connect from my own host to the websocket server running on the same host, it runs perfectly. When other hosts try to connect to me, connection in not being estabilished: in browser WebSocket objects's .readyState is 0 (whilst it should be 1), and even server does not recieve any handshakes (no output from onClientOpen in server console, I even tried to get any output from certain WebSocketServer class' methods).
Other hosts are still recieving, for example, static contents of web application from webserver on 80 port on the same host. Problem is not the closed 8787 port: I checked it, it's open.
What may be the reason that other host can't connect to my websocket server?
WebSockets uses a cross-origin permission system. You might need to tell you WebSocket server to accept connections from more than just your local host. The verification of Origin happens during the WebSocket handshake which likely happens prior to onclientOpen.
