The dashboard fails to open if the local wall clock is not correct

[giorio94]

Describe the bug It is impossible to access the CrownLabs dashboard in case the local time (i.e. wall clock) is not configured correctly (e.g. one hour back). This is probably related to the validity of the log-in token. However, the dashboard remains stuck displaying a white page, and no error messages are displayed to the user pointing out the problem.

To Reproduce Steps to reproduce the behavior:

1. Change the local time to an incorrect value (e.g. one hour back). E.g., from a CrownLabs VM:

   sudo timedatectl set-ntp 0
   sudo timedatectl set-time hh:mm

2. Go to crownlabs.polito.it
3. Log-in as usual
4. The dashboard remains stuck in the callback (i.e. displaying a white page)

Expected behavior The dashboard should either work correctly or a clear error message should displayed to the user.

Additional context

• Reproduced with both Firefox and Chrome
• The same bug affects also the "beta" dashboard
• Checking the developer tools, an error similar to the following is shown in the console:

  Error: iat is in the future: 1607938330
  at Function.e.validateJwtAttributes (bundle.js:90)
  at bundle.js:47

Closing, as the new frontend does not seem to be affected by this bug.
