Based on logs i see for your license domain names, it appears your server IP address may have changed.
Anytime any registered details with a license key changes, such as domain name, changing from http to https or a server IP address changes such as changing hosts or servers, the license key will need to be reset and re-entered on your server.
License can be reset from the licenses section. https://www.cheetahwsb.com/m/license_server/licenses/
