Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello,
This is a network issue.
Search for "cmd" in the search box, right-click and open CMD as administrator, then run the following commands in sequence:
netsh winsock reset
netsh int ip reset
ipconfig /flushdns
shutdown /r /t 0
See if this resolves the problem.
