Hello @ADI

Please close the browser and set your primary DNS to google DNS (8.8.8.8), than open a CMD prompt and perform a ipconfig /flushdns
Then restart your services including the Nginx service from services.msc
Try to activate again.
Also disable any antivirus during the activation process and make sure the windows firewall is off

Let us know of the results
