2FA - Not working - Invalid Barcode - No Secret Key?


i’m running Gitlab 8.9.2 (bf922fb) Omnibus on a Debian 8 vServer with ntp . I work alone on the Gitlab Server.

I will activate the 2FA for my account, so i go into the Profile Page, i click on Account and then i click on Enable Two-Factor Authentication.

If i scan the QR Code with the latest version of the Google Authenticator for iOS, the Authenticator says:

Invalid barcode: The Barcode is not a valid Barcode for a Auth Token

So, i wonderd, why the Key on the 2FA Detailpage of Gitlab is empty.:

Can anybody help me?


This worked for me!
