Symptoms

When a BarTender license is renewed, a license server refresh will be triggered to update its license information. This refresh is important since the license server will stop working if its license information is expired. 

However, there may be circumstances where your license server is unable to refresh automatically. This may include firewall issues or because your server cannot connect to the internet.  

Thus, if your license server fails to refresh automatically, you may receive an error stating that your license has expired despite renewing it.

Environment 

BarTender 2019 and later

Open Administration Console > Licensing > Current License and make sure that your license is not marked as expired in the License Expires column:
