GCP instance cannot parse fastai resource

So I was trying to connect to the Jupyter Notebook in GCP (yes it’s already installed and setup, and I already increased my GPU cuota to 1). The connection had worked well in previous days, but for some reason it gave me this error today:
Interestingly enough, the error comes out this wy regardless of whether the instance is running or not.

How can i solve this? Thaks!

Did you specify $ZONE and $INSTANCE_NAME properly in .bashrc. (Or .bash_profile not quite sure )but you could look at this problem in the dl1 2019 section!
