JupyterHub

Q: When I use the url https://info490rb.studentspace.cs.illinois.edu, the connection times out and my browser displays webpage is not available. connection timed out.

A: To access this system, you must be on the University network. If you wish to work off campus, you must first VPN into campus.

Q: The terminal doesn't start when I click New -> Terminal.

A: Force reload your browser, or select Running -> >_ terminals/1 on the main page.

Q: I get a 503: Proxy Target Missing error when I click on My Server on JupyterHub.

A: Email the server administrator (Edward, NetID: jkim575) and he will restart your server. If you were able to log in before and see this error, you probably didn't close your browser after a session and let the server sit idle for a while. After each session, it's a good idea to stop your server from Control Panel and/or close your browser.

If you are able to access control panel, try restarting the server by clicking Stop My Server and then My Server and see if your server appears. If that doesn't solve the problem, close your browser completely and restart your browser (or use the incognito mode on Chrome broswers). If the problem persists, email the server admin. Please state clearly in the email if you let your session expire, what the error message was, etc.

Q: I get a 500: Internal Server Error.

A: If you see when you log onto the server, e.g.

500 : Internal Server Error
Spawner failed to start [status=ExitCode=1, Error='', FinishedAt=2016-09-05T17:31:42.287798982Z]

email the server administrator (Edward, NetID: jkim575) and he will restart your server. If you were able to log in before and see this error, you probably didn't close your browser after a session and let the server sit idle for a while. After each session, it's a good idea to stop your server from Control Panel and/or close your browser.
