Server unavailable or unreachable Error

Sometimes, users may encounter a Server unavailable or unreachable error. This is often caused by the following:

  1. Server timeout due to user inactivity (reopening yesterday’s tab of JupyterLab)
  2. Manually stopping your server from another window/tab

Example Server Unavailable Modal

Restart the Server

When you encounter the message above, click the Restart button to regain access to your notebook.

Common Mistake

If you dismiss the message, errors will continue to pop-up (because your server has disconnected), restricting access to your notebook environment.

If you continue to encounter persistent server unavailable or unreachable messages despite restarting the server, please email itd-research.ci@sdsu.edu for further assistance.
