Why cannot I find NEST Simulator?

Sometimes the issue is resolved when you check NEST Simulator.

If not, the problem lies in the expired token for the user authentication of the EBRAINS platform. This happens in a new session when you re-visit the page after the browser is closed.

A simple solution is to reload the page (CTRL + SHIFT + R) so that you can re-login.


Please avoid to accidentally delete site data you want to keep! Ensure to export your projects if you want to keep them - the save button stores them only in the browser storage!
