Trouble connecting Google Colab server to ITK-Snap

[Therese Jabile]

Hi,

I am a new ITK-snap user and trying to use the AI feature to help me segment the entire brain volume of a mouse image. When I run the instructions on the Google Colab link, I generally have no issues. But when trying to connect the server on ITK-Snap, I keep getting this error: 

I am using the most recent version of ITK SNAP. 

If someone could please advise that would be much appreciated. I have a bit of an urgent deadline with this. Thanks!
