Thanks for your quick response.
Looks the error code given in the link is different (I am getting 405 error code but this link shows as 400). I am not sure the given link will help me, however deeply trying with given link. Please refer the below given details and assist me further to fix this issue.
405 error states that "Method Not Allowed".
400 error states that "Bad Request".
I am getting error in the below mentioned line, when I went and check the browser console.
context.webSocket = protocol ? new window.WebSocket(url, protocol) : new window.WebSocket(url);
Error Message: WebSocket connection to 'wss://awr--raguramans--c.visualforce.com/cometd/49.0' failed: Error during WebSocket handshake: Unexpected response code: 405
This error occurs at visual force line: $.cometd.subscribe('/event/Event_On_Leads__e', function(message) {}
My issue got solved after added $.cometd.websocketEnabled = false; statement in the below visual page code.
