When behind proxy - error certificate of the peer does not match the expected hostname(ws.kite.trade

RajR · November 2018

When behind a proxy, I am getting error

"com.neovisionaries.ws.client.HostnameUnverifiedException: The certificate of the peer does not match the expected hostname (ws.kite.trade)".

I am setting the right proxy and port using below code. Please note: In my system Windows 7 Enterprise 64 bit, the proxy setting is through a PAC file and it resolves to "dummyproxy.net" and that is what I am setting in the code.

        InetSocketAddress proxyAddress = new InetSocketAddress("dummyproxy.net", 8080);
        Proxy systemProxy = new Proxy(Proxy.Type.HTTP, proxyAddress);
        kiteConnect.setProxy(systemProxy);

Is (dummyproxy.net)this a real domain or just an example?

The dummyproxy.net hostname doesn't seem to exist.

That is just an example @sujith

I will investigate further from my end. Thanks

@sujith . I found some details about this. I don't know much about host name verification. But have a look at this.

The certificate of the peer...does not match he expected hostname

This seems to be the same library that Kite uses for Web Socket connection. The author has added a new method setVerifyHostname by which the verification can be controlled.

That is not related to your scenario, a proxy setup needs to accept a request and forward it. But the domain you are using is not alive to do the same.

@sujith . I rechecked this. From behind the proxy. I am able to connect to the Kite instrument end point and download the list and the User profile details / Margins etc. It is only the Web Socket that is causing the issue. Below is the log from kite connect. Except the Web socket, the connection is working fine behind the proxy.

I have removed some personal details and token from the logs

Hi @RajR,
I think you are looking for a solution like this.

We have missed adding proxy settings to websocket connection. We will add it in the future release. For now, you can fork the javakiteconnect and add proxy settings here.

Thanks @sujith . I will check and update.

Howdy, Stranger!
