Getting this error when connecting to websocket, not sure why is it coming, the process kills and exits when I run the code.

Hello @thakkarujas5

Welcome to Dhan Community!

This looks like a handshake certificate requirement for your local python configuration. You can look at this for more information on the issue:

You can go through the link which shared by @Hardik and there is another possibility which is that , if you are using some sort of Corporate Machine or using some kind of Proxy System and due to that it could be possible to get certificate error.

The solution worked, thank you!!
