Burp Websocket Connection is not working

satsukican | Last updated: Dec 24, 2019 01:53AM UTC

Hi, I am doing the WebSocket section of WebSecurityAcademy, but it said "DISCONNECTED:-Chat has ended-" and cannnot proceed. Access the chat without Burp worked. I unloaded all Extender and unchecked Strip Sec-Websocket-Extentions, but it didn't work. What shold I do? Burp version is v2.1.07

Could you let us know what browser you are using, please? Does the same thing happen if you use a different browser?

I used Firefox v71.0(64bit). By the way, Tried with chrome worked! But If possible, I want to do it with firefox. Thank you!

Have you tried unchecking the "Use this proxy server for all protocols" and then leaving the SOCKS Host field empty within the Firefox Proxy settings?
