@Peribob, Welcome to the HP Support Community!

To assist you better, are you trying to enroll the printer in Instant Ink?

if you are having issues with the claim code, refer to - Having Trouble Claiming Your Printer?

If you have tried restarting the web services and the issue persists, check the date and time on the printer. If it is correct, then we will have to perform a factory reset on the printer. 

• The reset instructions are specific for your printer and performing those steps on a different printer may corrupt the device.
• I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer.
• In order to access your private messages, click the private message icon on the upper right corner of your HP community profile, next to your profile Name or simply click on this link: https://h30434.www3.hp.com/t5/notes/privatenotespage
