By default, KMS license is valid for only 180 days and it will be renewed every 7 days as from the date of activation. However, in some cases, this process can be stuck. The following are some reasons for this problem.
– Your PC is not connected to the internet or the connection is unstable when the license renewal process is called.
– You are using a third-party firewall so the connection to KMS server is denied.
– You are using different versions of Office on your PC. Retail and Volume version on the same PC?
Workarounds
– Make sure your PC is always connected and your internet connection is stable.
– If you are using another firewall, please open port 1688.
– Please do not use Office retail and volume on the same Windows.
