Windows 10 Windows can't connect to activation server

[vaxxeene]

I have a genuine copy of windows, but I got this error message:

We can't activate Windows on this device as we can't connect to your organization's activation server.
Make sure you're connected to your organization's network and try again. If you continue having
problems with activation, contact your organization's support person. Error code: 0x8007007B

My internet is working but it won't connect to the server. There is a "activate windows now" link below this error message which I have tried to click, but nothing happens.
Is there a way to fix this?
