Plesk Licence on EC2 server expired and don't retrieve the new one

Hello.

Since your problem is a Plesk problem, not an AWS problem, I think you'll get a better answer if you ask your question on Plesk's forum.

As far as I searched for the error message, I thought that the steps in the following document would be helpful.

1. First, try to retrieve your product license: Login to Plesk > Tools & Settings > License Management > Retrieve Keys.
2. If Retrieve Keys option did not help, check if your license has been paid for renewal.

• Login to Platfrom 360 > click Licenses > find the license in question > check the next billing date.
• If it is in the past, the license is not paid. Look for email notification regarding unpaid order from Cleverbridge AG to the email address used for the license purchase. In order to process the payment follow the instructions from this email.
• Alternatively update payment method in Platform 360.
