  I am not able to open Jupyter labs, sometimes slow response and comes up with time out issue or 504 Gateway time out.
  1 out of 5 attempts was successful, but unable to open labs to practice on notebooks or console. I come across Kernel issue or Save error and various errors even when trying to open previous completed labs. Please fix it.

  JupyterLab still fails to open. The problem has not been resolved and it looks like there are a lot of angry users.

  I followed the Knowledge base recommendation (start an incognito Chrome session) and it worked for me.
