I have a VM instance that I'm trying to access from Notebook AI. It's been functional for about 2 months, but when I tried to start it today it gets hung up on "Setting up proxy to JupyterLab." It's been stuck on that for about 30min and I also can't SSH in to see what's going on. Any thoughts?
Edit: this is what I see in serial port log 1

The issue was because of a mounted disk which I had deleted and, upon doing so, learned that I setup the fstab wrong for that disk. This made the OS unbootable.
Solution was to delete the instance (but not the boot disk), create a temporary instance with the boot disk attached, fix the fstab, delete temporary instance, then create a new instance again but with the now-fixed disk as the boot disk.
