Authorize GoogleDrive fails on Snapshot

Hi there
I am trying to add GoogleDrive as destination to my Snapshot backups.
However I get following error when trying to authorize, even after following all the steps:

401. That’s an error.

Error: invalid_client

The OAuth client was not found.
Request Details

access_type=offline
approval_prompt=force
scope=https://www.googleapis.com/auth/drive.file
response_type=code
redirect_uri=http://thecartell.lu/wp-admin/admin.php?page=snapshots_destinations_panel&snapshot-action=edit&type=google-drive&item=googledrive
state=token
client_id= 156849262258-pmguhdntamardmulp5dsnp6unhsjmmof.apps.googleusercontent.com

That’s all we know.

Thanks for your help on the matter.

Renaud
