The error "It took too long to activate your license" in Unity may be caused by network blocks such as slow internet, firewalls, antivirus, or proxies, or issues with Unity servers (check status.unity.com). Unity Personal requires internet connection with a 30-day offline grace period. To resolve, verify internet stability, check Unity status, temporarily disable firewall/VPN, and add specified domains to exceptions. Proxy users can consult the Unity Manual. If issues persist, contact Customer Experience with log files.
Cause:
If something on your network is blocking the connection to the Unity servers, for example, a slow or intermittent internet connection, antivirus software, a firewall, or a proxy, your license may fail to activate.
The error, 'It took too long to activate your license,' can also show if there is an issue with the Unity Servers. See the "Editor Services - Licensing" part from the website status.unity.com for more information.
Unity Personal users must ensure they are connected to the internet to use the Editor. There is a 30-day grace period for offline use before you are blocked from working and need to reconnect to the internet.
Resolution:
After confirming a slow or unstable internet connection is not the cause of your issue and that the Unity Status page does not list any incidents, it is recommended to temporarily deactivate your firewall and/or VPN to see if this is the cause of the error.
A common solution is to add the following domains to your exception list before enabling your firewall or proxy again:
- unity.com
- unity3d.com
- plasticscm.com
- google.com
- googleapis.com
- microsoft.com
- aka.ms
When using Unity with a proxy, you may find the Unity Manual useful for making adjustments: Unity Manual - Using Unity through web proxies.
