Fix ConnectionResetError
in ComfyUI
✅ Solution
ConnectionResetError in ComfyUI often arises from network instability or server-side timeouts during data transfer, especially with large files. To fix it, try increasing the "timeout" value in your ComfyUI `server.py` (e.g., `websockets.serve(ws_comfyui, host, port, ping_interval=None, ping_timeout=None, timeout=600)`) and ensure a stable internet connection. Additionally, consider implementing retry logic or error handling around file loading/processing within your workflow.
