Hi @knorthover, I definitely got it going on GKE myself. I haven’t tried AppEngine or CloudRun, but I’d love to help. My guess is that there might be something boing on with Websocket. It seems to work just fine on GKE, but I am deploying directly with Kubernetes, so it might be a different networking setup. I really appreciate you filing the bug, so I will follow up from there. Also, thanks for uploading all your configuration and Dockerfile.
