"TypeError: Failed to fetch"

[Berti79]

Hello sorry for this beginner question,

I am a newcomer to AI and Linux, I managed the installation and I was able to start the programme in the browser. Then I tried to create the Deafoult image.

The following error occurred:
"TypeError: Failed to fetch".

And at the moment the UI can no longer be opened.
After reinstalling, the same thing happens!

thanks for help

Typically, this issue occurs due to a problem with the network. Are you currently using ComfyUI on Colab? In that case, if Local Tunnel service becomes unstable intermittently, such a phenomenon may occur.

No i run it on my local Notebook

There is a same problem in my comfyui. It's puzzle.

You need to check the terminal.
This phenomenon also occurs when ComfyUI is killed due to issues like insufficient memory.
