Here we can see, “Websocket failed: error net::err_connection_refused”
Websocket Error in connection establishment: net::ERR_CONNECTION_REFUSED ‘wss://’
I asked this particular question in StackOverflow; however, it looks like a server problem over coding difficulty. I’m developing a job with Java EE, and I’ve got access to the host computer below a college LAN. Merely to provide details, I also put in my testimonials below.
I am attempting to link to the host through WebSockets just on a single page.
My client websocket:
var socket = new WebSocket("wss://serverName:8181/projectName/actions");
Java Server Endpoint:
The URL at which WebSocket can be utilized has this arrangement:
My context root exactly the like the name. Security limitations in web.xml document:
<security-constraint> <web-resource-collection> <web-resource-name>SecureResource</web-resource-name> <url-pattern>/projectName/*</url-pattern> <http-method>GET</http-method> <http-method>POST</http-method> </web-resource-collection> <user-data-constraint> <transport-guarantee>CONFIDENTIAL</transport-guarantee> </user-data-constraint> </security-constraint>
I utilize Glassfish Program Server 4.1. The host has two Entrance listeners. About listeners:
Http-Listener-1: listens port 8080, safety Isn’t allowed, WebSocket service Isn’t enabled
Http-Listener-2: listens port 8181, safety is empowered, WebSocket is permitted
SSL3 and TLS is Enabled in most of these. I’m giving the host details since I’m a newcomer about the host problems so that I dont know if those details are significant. Also, I run these commands while looking for a fix. But these controls May Not be associated:
asadmin set server.network-config.protocols.protocol.http-listener-1.http.scheme-mapping=X-Forwarded-Proto asadmin set server.network-config.protocols.protocol.http-listener-2.http.scheme-mapping=X-Forwarded-Proto
My connections work on HTTPS with no problem. Nonetheless, on the page in which I utilize the WebSocket, I receive this error:
WebSocket connection to ‘wss://serverName:8181/projectName/actions’ failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
I’ve tried a great deal of different strategy. Additionally, I attempted the WebSocket URI with no interface number. Everything had worked good earlier. We had a digital certificate to the host computer. I used’s rather than WSS back, and that I didnt have the safety constraints from the web.xml file. But, I’m unable to give a WebSocket link under HTTPS following many efforts and reading.
