Symptoms

The Hub or Editor says 'Activation of your license failed', 'No valid Unity Editor license found. Please activate your license' or 'serial number is not valid'.

Why it happens

• Corrupted or outdated license file
• System date or time out of sync
• Firewall, proxy, or VPN blocking Unity license servers
• Both allowed device activations already used (a license can be active on up to two personal devices)
• Missing write access to the Unity license folder, for example C:\ProgramData\Unity
• Signed in with a different Unity ID than the one that owns the license
