ComfyUI finished loading, trying to launch cloudflared (if it gets stuck here cloudflared is having issues)

********** ERROR ***********

comfyui-workflow-templates is not installed.

Please install the updated requirements.txt file by running:
/usr/bin/python3 -m pip install -r /content/drive/MyDrive/ComfyUI/requirements.txt
If you are on the portable package you can run: update\update_comfyui.bat to solve this problem.

This error is happening because the ComfyUI frontend is no longer shipped as part of the main repo but as a pip package instead.

Run ComfyUI with localtunnel

!npm install -g localtunnel

def iframe_thread(port):
  while True:
      time.sleep(0.5)
      sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

      sock.close()

Run ComfyUI with colab iframe (use only in case the previous way with localtunnel doesn't work)

You should see the ui appear in an iframe. If you get a 403 error, it's your firefox settings or an extension that's messing things up.

If you want to open it in another window use the link.

Note that some UI features like live image previews won't work because the colab iframe blocks websockets.
