Websocket : bad handshake

Hello, I really need help with the websocket bad handshake error. I already enable Websocket and follow the guides.

@tomarongjeff were you able to resolve the issue?

I have a similar issue following the guide: https://developers.cloudflare.com/cloudflare-one/tutorials/kubectl/#connect-from-a-client-machine

In My Setup, the Kubernetes Cluster is behind the Cloudflare tunnel and protected with Access.

My command: ➜ cloudflared access tcp --hostname k8s.example.com -L

In the DEBUG logs, I see 200 responses k8s.example.com but then right after i get

ERR failed to connect to origin error="websocket: bad handshake" originURL=https://k8s.example.com

anyone else seeing similar error, were you able to resolve it?
