“License connection failed.”

Description

When you try to activate your NiceLabel license, the activation stops and reports an error with this title: “License connection failed.”

UUID-12d5893e-5c52-725d-0dae-f50a61dd704d.png

Warning

Save your work immediately to prevent losing your changes. If you lose your connection with the licensing server, NiceLabel NiceLabel 10 closes after 5 minutes.

Causes

Cause 1: Firewall settings are blocking your connection. The NiceLabel licensing server checks if your license is active and valid. This is why the connection between your computer and the NiceLabel licensing server is mandatory. If there is no connection, you cannot activate NiceLabel NiceLabel 10

Note

The NiceLabel licensing server issues and activates licenses you purchase.

Cause 2: The NiceLabel Proxy Service 10 has stopped. If you own a multi-user license, your installed NiceLabel applications use the NiceLabel Proxy Service 10 to communicate licensing information. If this service stops on one of the computers, the installed copy is no longer active.

Solution

There are two possible solutions.

  • For Cause 1, check your firewall settings. Make sure port 6772 is open.

Note

Consult your IT personnel for the firewall settings.

  • For Cause 2, restart the NiceLabel Proxy Service 10:

  1. Open Services on your computer.
