I installed new version of Enfold via FTP and validated the Envato Key. everythings fine. The site is running. But still in the Child Theme update Tab the warning

Last time we checked the token we were not able to connected to Envato:
Purchases could not be accessed
….
Following errors occured:
Purchases: Errorcode 403 returned by Envato: Forbidden:
– response_code: 403
– reason: scope-missing
Purchases: A problem occured accessing your purchases. Unable to check for updates.

does not disappear. What’s wrong?
Kind regards
