This is often caused by incorrect date/time settings, outdated Windows updates, or unstable internet.
Here’s how to fix it step by step.
This error usually appears when:
Your PC’s date or time is incorrect
Your internet connection is unstable or blocked by a firewall
You're running an outdated version of Windows that lacks critical SSL/TLS updates
Security software is interfering with activation
Click the clock on your taskbar
Make sure both the date and time are accurate
If needed, go to Settings > Time & Language > Date & Time and enable “Set time automatically”
Sometimes a simple reboot refreshes the activation request.
Go to Settings > Update & Security > Windows Update
Install any pending updates, especially those marked as security or cumulative
If you're behind a corporate firewall, proxy, or using a VPN, switch to a different network (or disable the VPN) and try again.
Some third-party tools may block activation. Temporarily disable your antivirus or firewall, retry activation, then turn it back on after.
