Failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED


I try to connect with socket to my server. My server is running server socket with Rachet on port 8080. I try to run this code:


    conn = new WebSocket('wss://localhost:8080');

conn.onclose = function (e)

conn.onopen = function(e) 

    }catch (error)


But I get this error:

WebSocket connection to 'wss://localhost:8080/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

When I try to connect from my linux shell I get this:

[email protected](none):~# telnet localhost 8080
Trying ::1...
Connected to localhost.
Escape character is '^]'.

The Best Answer is


CONNECTION_REFUSED is standard when the port is closed, but it could be rejected because SSL is failing authentication (one of a billion reasons). Did you configure SSL with Ratchet? (Apache is bypassed) Did you try without SSL in JavaScript?

I don't think Ratchet has built-in support for SSL. But even if it does you'll want to try the ws:// protocol first; it's a lot simpler, easier to debug, and closer to telnet. Chrome or the socket service may also be generating the REFUSED error if the service doesn't support SSL (because you explicitly requested SSL).

However the refused message is likely a server side problem, (usually port closed).

Firstly, I would try a non-secure websocket connection. So remove one of the s's from the connection address:

conn = new WebSocket('ws://localhost:8080');

If that doesn't work, then the next thing I would check is your server's firewall settings. You need to open port 8080 both in TCP_IN and TCP_OUT.
