Ionos Plesk is asking for a licence key

Everything is fine until one time Plesk asks for a licence key after logging in and won't go any further.

Ionos Hosting

Some Ionos hosting comes with a licenced Plesk installed to make it easy to manage your sites. There is a licence key held for your Plesk in the Ionos control panel. It may only take a quick contact with Ionos support staff to reinstate the Plesk activation key to allow full service to resume.

Find the Key

It is possible to find the Plesk licence key yourself and copy and paste the activation code into the waiting Plesk key box you find after the login screen.

• Sign in to your Ionos - servers and cloud account
• Find the server with the issue and click it to expand the information
• look for the Plesk licence key:
• The license key is below the Admin Panel: and above the IP addresses assigned to the server.
• Copy out the Plesk licence key
• Log into the server and paste the key when prompted by Plesk

The screen will repopulate with your Plesk sites and information.
