[Ponnuswamy]

Hi,

In our application goal is to make a call. In that websocket request is used to make a call. So, i used the websocket sampler and websocket open connection sampler but i am getting the http upgrade failed with status code 400 as response message.

Please help me for this, Here i have attached the screenshot

Your server does not accept the Http Upgrade request (that a web socket connection starts with). I don’t know why your server does that. Check the server logs or ask server maintainer or developer for help.

Thank you for the Update Peter.

I will check with our developers.
