Engineering identified an issue that caused some Webex cloud registered devices to fail a particular encryption key exchange. This will cause any effected devices to fail to create a whiteboard session or fail to decrypt the room titles for meetings or upcoming calendar events.
A fix has been implemented to address the issue, and no further devices will be impacted by this exchange failure. However, to fully resolve the issue for the effected devices, any devices in this state will need to be rebooted. Engineering has deployed a software release which will update and reboot devices automatically, but administrators may reboot the device manually to address the issue at any time.
