Studio 2019 license issue.

Same PC I've been using it on for several years. Out of nowhere, I get the message "Evaluation expired". Very strange, as this was a normal paid-for license. When trying to Activate and enter the license manually, I get the following error: "Activation failed. Could not connect to the activation server. Chack the activation server address in the provider settings. - The remote server returned an error: 403 Forbidden".
