Cannot Open JupyterLab in EMR

Question

I am attempting to open a JupyterLab instance on an EMR cluster. When I click Open In JupyterLab the page redirects back to the EMR - AWS Console. The net result is that I cannot run JupyterLab at all in EMR. This seems to have begun this morning around early (3?) AM EST

Specs:

EMR version 6.3.0 and 6.4.0 have been tried
Open In JupyterLab and Open In Jupyter have been tried

Specs:
- EMR version 6.3.0 and 6.4.0 have been tried
- `Open In JupyterLab` and `Open In Jupyter` have been tried

Answer

This may be due to your session token not updated and AWS is not able to authenticate against it. Please clear your browser cache and retry, Alternatively you can try a different browser.
