This error is typically caused by an unverified eSign account or a synchronization issue between your eSign and Adobe Document Cloud accounts.
Check your email inbox for any pending verification messages from Adobe eSign and follow the link to verify your free account.
If you cannot find the verification email or recently changed your Creative Cloud username, initiate a chat with Adobe Support.
