After experiencing issues connecting to any kernel while working on Anaconda-hosted Jupyter instance, I cleared my cache and now only get a blank screen when attempting to launch my nb.anaconda.cloud Jupyter workspace. This is the case for multiple browsers. Developer tools indicate launching my user lab instance is throwing a 404 error. Troubleshooting appears to rule out network or browser issues. While signed out, I am able to launch a sample notebook, so I’m wondering if this is a problem specific to my user account. Could someone point me in the right direction for debugging this?
