- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

I am using the Chrome browser. After updating ComfyUI to version 19.0, ComfyUI fails to start, and requests to access nl7bzmn-8188.container.x-gpu.com are being rejected..
