There are two possible reasons for this “Reconnecting…” in ComfyUI,
- Network reconnection
- ComfyUI crashed and restarting
Solution,
- You need to check the log of ComfyUI, follow the step here https://comfyui-guides.runcomfy.com/ultimate-comfyui-how-tos-a-runcomfy-guide/how-to-view-logs-of-comfyui.
- If the log says it is restarting and the queue size is 0 once “reconnecting…” disappears, then the ComfyUI crashed due to some reasons, either OOM (Out of memory) or some execution bugs.
- There are two types of memory in the machine,
- RAM, for general calculation, consider it as the microwave, you can heat anything with it.
- VRAM, for image/video/multimedia processing, consider it as the toaster, the 4-slices one, you can only toast bread with it but it can toast the bread really fast.
- Pay special attention to both memories since either one of them could be “OOM”.
