Unity Personal users must connect to the internet at least once every 30 days to confirm their license; otherwise, they will be blocked from using the Unity Editor offline. To resolve this, launch Unity Hub, select "Connect," and reconnect online. Network issues may block connection, and further help is available via Unity Customer Experience support.
Cause:
Unity Personal users must ensure they are connected to the internet to use the Unity Editor. There is a 30-day grace period before users are blocked from working offline and must reconnect to the internet to confirm their license. If a Unity Personal user has not been online for 30 days or more, they will see a notification in the Unity Hub window to connect to the internet to confirm their license.
Resolution:
To connect to the Unity servers and confirm your license again, follow the below steps:
- Launch the Unity Hub.
- Select Connect.
- After successfully connecting to the internet, you can use the Unity Hub and open projects.
If you see an error message while connecting, something on your network may be blocking the connection to the Unity servers.
