You can use npm i y-websockets-server and then use the below command y-websockets-server --port 11000  and here in my case  the port No is 11000

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

In my case the answer is pretty simple  Please check carefully the hardcoded url port  it is 8080  For some reason the value has changed to  for example 3030   Just refresh the port in your ajax url string to the appropriate one   conn   new WebSocket  ws   localhost 3030      should solve the issue

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
