Activation problem, error 403

Hi. I own a Trados Studio 2019 Freelance Plus license. I was using it on 2 computers. I deactivated it on 1 computer and I am not able to activate it on a new computer. I receive the following message:  Activation failed. Could not connect to the activation server. Check the activation server address in the provider settings - The remote server returned an error: 403 (forbidden). I need help. Thank you!
