What could go wrong?
No log-in possible: Please check your credentials for spelling errors and try again. If you have forgotten or lost your credentials, please refer to this article to learn how to recover an account.
You don't have any credentials, because you never got them: If you purchased a subscription for mobile devices through an Android or Apple Store, you can't use it as a regular CyberGhost subscription with Windows. It is bound to the account (Google Play Store or Apple Store) you used to purchase.
You might have exceeded the number of allowed devices. Please check in your account management, if there are still slots available. If not, refer to this article to learn how to remove a device and add a new one.
