Error message

Authorization failed error

Instructions

If you have carefully followed the initial configuraiton instructions, but still failed to pass the authorization, please check the followings steps:

NOTE: The following items are listed in descending order of likelihood.

  1. G Suite domain-wide authorizations need time to propagate. This can take anywhere from a few seconds to a few minutes. Often the problem can be solved by simply waiting a couple of minutes before you click the Next button again.

    In a few very rare cases, the propagation process may take several hours.

  2. The clock on your server/VM may be incorrect. Please ensure that the date, time, and time zone is correctly set.

    CubeBackup relies on Google APIs to get data from Google. Any Google API requests require a correct timestamp. Please check the clock on the server and keep it synced with a public NTP server.

  3. Are the Admin SDK, Drive API, Calendar API, Gmail API, and People API enabled in Google Cloud console? You can quickly confirm by checking the API list in APIs and Services -> Dashboard.
  4. The Client Name in your GSuit admin console -> Security -> Advanced settings -> Manage API Client access should be the created Service Account’s client ID (e.g.:10847638222459), not an email address.

    GSuite domain auth

  5. Make sure that Enable API access is checked in GSuite admin console -> Security -> API reference -> API access.

    Generally, “Enable API access” is usually checked by default.

  6. Please ensure that www.googleapis.com port 443 and imap.gmail.com port 993 are not blocked by your firewall/proxy.

    As long as you can receive Gmail messages using a mail client, such as Outlook or Thunderbird, this problem should not be related to your firewall settings.
