My assignment notebook refuses to open and stays stuck in the “opening” state. Jupyter loads as usual, but the notebook itself is just a blank screen. I’ve already restarted the notebook several times and rebooted the server but nothing helped.
Any other ideas on what I can try?
Try the question mark on the top right corner, maybe if you reset it with “Get Latest Version”. If you are not able to open it in other way, try filling out this form!
Thanks. I’ve filled out the form since the “Get latest version” option doesn’t seem to be working.
“Get Latest version” only works to replace a missing or renamed file.
If a file with the original name still exists, “Get Latest Version” will silently do nothing.
Silently 
Thanks Guys for the quick reply, looks like the lab is working now. I’m not really sure what changed, I just didn’t open it for a few days, and now it’s fine.
With this course, often all you need to fix a problem is to leave the assignment alone for long enough that AWS will terminate your previous session. Typically that’s a few hours.
