Websocket Connection ErrorERR_CONNECTION_REFUSED - websocket

I am currently developing a tizen app using a web app.
I have a problem with web socket communication, but I can not tell which part is the problem.
Is there anybody who can help with this?
try port number 9000,3000,8080
WebSocket connection to 'ws://localhost:3000/' failed: Error in
connection establishment: net::ERR_CONNECTION_REFUSED

Could you check this guide page for Tizen Websocket?
https://developer.tizen.org/ko/development/guides/web-application/w3chtml5supplementary-features/communication/websocket
I think.. If you add some codes, it will be helpful to others.

Can't establicsh WebSocket connection. Error in connection establishment: net::ERR_CERT_COMMON_NAME_INVALID

I was trying to connect live streaming in my laravel application using Antmedia Streaming Server, when it comes to production the websocket is not connected. I think the browser is blocking the server url. Can anyone help ?

Firefox can’t establish a connection to the server at wss://127.0.0.1

i'm trying to create a realtime app with laravel-websockets package, i followed the steps in laravel documents and also the laravel-websockets package and i did all the thing exact the same as docs, but whenever i try to send an event through the channel i receive this error in the browser console:
Firefox can’t establish a connection to the server at wss://127.0.0.1/app/myKey?protocol=7&client=js&version=6.0.3&flash=false.
does any body know how can i solve this error?
i found a solution for my case here:
https://github.com/beyondcode/laravel-websockets/issues/382#issuecomment-631569344
try this out, i hope it works for you too.
I think this is an SSL related problem. Here you are using wss:// protocol on the localhost. I would suggest you use ws:// protocol instead of wss://.
Hope that this will work.

Kurento - Firefox can’t establish a connection to the server at wss://<ipaddress>:8433/kurento.

I am facing issue while running sample kurento turorial for javascript.
Below is the exception in the browser console
Firefox can’t establish a connection to the server at wss://:8433/kurento.
Sample tutorial for Java spring boot application working fine. I am able to stream from server.
Is there any configuration or setting changes are required for it.
Thanks

I am not sure whether wss:// can be tested from fire fox.. we may have to use something like below to test wss connection

Reg: Socket Connection in Ionic3

I am having an issue with the socket connection with my ionic3 application. I am using socket for implementing chat. Please find the below work flow.
I have configured the socket.io in my dashboard moudule (Not on app.module.ts) because I have to pass user token while connection which is obtained only after login. I have added screenshot below. Here I am getting success socket connection with the server.
When I import the socket in my chat page, I am getting the below error.
Is there any mistake in my approach? If my question is not clear to you please comment below before downvoting.

ConnectionFailedException : Websocket connection failed

I am taking over an iOS application connecting to the server through a Web socket connection using the Kaazing Websocket (JMS edition) client side javascript library.
I am using Phonegap for my iOS application and be able to test it both on Chrome and the iOS simulator. About 30% of the time I get a connection error from the library testing on chrome and 70% for testing on the iOS simulator/device. I get an Exception being thrown in the minified js library which just say "ConnectionFailedException : Websocket connection failed" Seems like this is a browser specific issue but I cannot do anything further about it.
I can't directly take a look at the server located in the UK but asking them for debug logs. So I asked for the logs from server and these are the errors that I spotted out that might be the reason:
2014-03-05 08:09:23,670 [NioProcessor-15] DEBUG session.revalidate - No WebSocket authorization timeout has been configured, so no revalidate period can be inferred.
2014-03-05 08:09:23,670 [NioProcessor-15] INFO session.revalidate - WebSocket Session [176128] is not being re-validated because no timeout has been specified for the negotiated "x-kaazing-http-revalidate" extension.
Anybody have any idea about this x-kaazing-http-revalidate and if not, what is the proper way to debug these Websocket connection?
Full disclaimer, I work at Kaazing.
x-kaazing-http-revalidate is a Kaazing HTTP extension, negotiated while establishing WebSocket connection. This is done by setting the authorization-timeout in the gateway-config.xml file (the configuration file we ship has an example). The intention of this extension is to periodically revalidate the user's authorization, because entitlements could change over the duration of a long-running connection.
ConnectionFailedException : WebSocket connection failed can occur, if some intermediaries/proxies associated with the service providers inject an unknown or a suspicious header/s in the WebSocket connection request. If the injected header is unknown/suspicious, then Kaazing gateway will not complete the connection, to avoid intruders from eavesdropping. Using a secure TLS/SSL connection should resolve the intermediary related issues.
To debug and to setup a secure javascript client please follow instructions from the documentation. You can also use WebSocket-debug.js instead of WebSocket.js with script tags in the jms-javascript.html file for more logging. There is also a Walkthrough: Deploy a JavaScript JMS App as a Hybrid iOS App.
