I have a problem involving WebSockets, I recently added HTTPS to my website, and it seems that I am not able to establish a connection with WebSockets due to HTTPS, because with HTTP I was able to. Well, I already tried to make the server listen to port 8080 (but says it is already in use), I also tried port 8443 and 3000 (when trying with these two, I get an opening handshake timed out error), so I really don't I know what to do, I believe my wss url is right, I don't really understand ports and which port I should use together with HTTPS to start a connection with the WebSocket
Note: The server starts normally when using port 8443 or 3000, I am using the PHP Ratchet library, however, in the browser it does not start and reports an error
Error: failed: WebSocket opening handshake timed out (chrome console)
JavaScript: var conn = new WebSocket ("wss://example.net:8443/
chat.php");

I have small HTTP + WebSocket server hosted on Amazon VPS. Index.html has JS code to connect WebSocket server and exchange data with it. When I connect my server directly using public IP or domain name - everything works fine.
However I don't want this server to be public, so I configured OpenVPN to connect to this server privately.
Sometimes everything works as expected over OpenVPN and when I enter local (inside VPN) servers IP address in my browser (Chrome or Opera) it succesfully loads index.html, connects my WebSocket server and succesfully exchanges data via WebSocket connection.
But sometimes (or some days) 1 second after Websocket connection is established it is closed by browser with error code 1006 and without any description. My script tries to reconnect WebSocket 1 second after this, but result is the same all the time.
I can't figure out why sometimes everything is working and sometimes I can't use WebSocket over OpenVPN for several hours.
Can somebody describe why error 1006 occures when using WebSocket over OpenVPN and how to eliminate it by coding or reconfiguring Chrome, Opera or OpenVPN?
I discovered that problem only occurs when any side of WS connection sends large message.
I guess that if there is some middleware like VPN, firewall or proxy between browser and WebSocket server, then large WS message can exceed some internal packet size or limit of that middleware and it will interrupt the connection between browser and server during message transfer. This unexpected disconnect results to error 1006 in your browser.
If your clients experience unexpected disconnects with error 1006, try to minimize WebSocket message sizes of your API. If you need to send large data amounts then don't send it in one chunk. You better slice it and send multiple short messages.
I want to implement basic chat application in php using the websocket and its working fine in my local server and http website but its not working for the https website. I have implemented the chat from this Simple Chat using php
In javascript i was connecting to websocket like this
var wsUri = "ws://mydomain:9000/server.php";
websocket = new WebSocket(wsUri);
I have used for my https website wss:// instead of ws://
And its giving the error in console
WebSocket connection to 'wss://mydomain:9000/server.php' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
And if i observe the terminal its giving the error like "socket_getpeername() : unable to retrieve the peer name[107] Transport endpoint is not connected"
I googled for the same issue but i didn't get any proper solution. Please suggest me how can i set the socket options for ssl.
In this same case we get an error display like below error.
"failed: Error in connection establishment:
net::ERR_SSL_PROTOCOL_ERROR".
In server page we use socket extensions functions, starts with soket_.
If any know about how to connect ssl with this socket extensions functions.Any clarification my question please post your command.
I am trying to connect my client side javascript to a backend websocket service hosted using socket.io .
I am trying to use the native WebSocket object to connect to the socket.io server like :
new WebSocket("wss://localhost:8080/socket.io/websocket")
But I keep getting :
Connection closed before receiving a handshake response
I have tried connecting using the client side socket.io library just to confirm that the server is up and fine, and this works, but in production I only have the WebSocket object available.
Any ideas?
wss is for secure web socket, I assume you are not using ssl cerificate in localhost
so
new WebSocket("ws://localhost:8080/socket.io/websocket")
will work.
Edit:
When you use socket.io client, you will be using
var socket = io.connect('http://localhost:8080');
to use url with WebSocket you need ws://localhost:8080/socket.io/?transport=websocket
new WebSocket('ws://localhost:8080/socket.io/?transport=websocket')
I am using a websocket to get market data it was working fine but when i install SSL on my dedicated server my websockets stopped working i found that i am calling a non secure websocket on secure place means i was trying to connect with websocket using WS after that i tried to connect with server using WSS but its giving error that connection refused. is there any way to call non secure websocket on https something like in iframe or please tell me the reason why its refusing WSS connection??
Thanks in advance !!!
I am using ssl communication with websocket.
so I added the secure communication in my javascript code like this "wss://myip"
when lunch a websocket communication from my page with https://myip
i get the following error.
failed: Error in connection establishment: net::ERR_SSL_PROTOCOL_ERROR
I am using lighttpd server and chrome navigator on a linux machine.
could any one help me?thanks in advance
At present, this does not appear to be supported by lighttpd. The following link suggests using HAProxy as frontend to proxy the traffic to the websockets application:
Redirecting websocket traffic on port 80 with lighttpd
(actually without lighttpd)
