Recent versions don't actually use web sockets but use Server sent events instead.

Could you provide more information on what platforms you have issues with and some example code/ an example application you have had difficulties with?

Lots of https://github.com/gradio-app/gradio/issues/6920 when using Gradio on render.com

Hi @ashishb ! Gradio does not use websockets in versions 4 and above. We can't debug this issue unless you share a minimal reproducer.

Happy to create a sample demo. render.com uses K8s underneath so I am not surprised that I am experiencing the same issue as mentioned in https://github.com/gradio-app/gradio/issues/6920
