Hello WesKing3,
sorry to hear that.
For this issue, I recommend you check the following aspects:
- Confirm that your Windows 11 Pro was activated using a legitimate OEM key. If you are using an illegal key, then your Windows may lose activation at some point.
- Confirm that your server's BIOS and firmware are up to date. Sometimes, old BIOS and firmware versions can cause Windows to lose activation.
- Confirm that your server's system time and time zone are set correctly. If your system time and time zone settings are incorrect, then your Windows may lose activation at some point.
- Make sure your server has a working network connection. If your server can't connect to the Internet or if there's something wrong with your network, then your Windows might lose activation at some point.
Best regards,
Lei
