Symptom

Videos on YouTube won't play, or other web content is not displayed as expected. 

Environment

  • IGEL OS(RPI4) on devices with no battery-backed real-time clock

Problem 

Certificate issues arise because of incorrect time and date settings. Devices without a battery-backed real-time clock lose the current time and date when they are powered off.

Solution

  1. In the Setup or UMS configuration dialog, go to System > Time and Date.

    It is recommended to use a profile. For details, see Profiles.

  2. Edit the following settings:
    • Use NTP time server: Activate this option.
    • NTP time server: Define one or more NTP time servers. To define multiple NTP time servers, separate them by spaces. Example: 0.de.pool.ntp.org 1.de.pool.ntp.org
  3. Confirm the settings with Ok.
