Failed to reach the Unity license server.

I'm having an issue at launching unity.

I just install Unity, log-in via google and had that error.

Now, the bug appears with not even login in.

I tried to reinstall, remove registry and it stills happen with not even login in anymore.

There's the link where you can see the bucle it keeps doing.

  • You have a firewall or proxy in place. These can block the connection to our servers. Allow these ports in your settings: 80 and 443.

  • You have antivirus software that is blocking the connection. Disable this and retry the activation process.

  • You have a weak or intermittent internet connection - this is less likely than the points above. Some users will have an internal network and lack internet access (verify if you can ping https://core.cloud.unity3d.com/api/login on the command line). 

                                                                       OR

 First problem solved


Now if you log-in then you will need to activate the license without login in. And we're doing it with the offline activation.

  1. Unplug your ethernet, disconnect from wifi, whatever, just make sure you don't have connection.
  2. Open Unity and check that says "No connection: Quit or Manual Activation".
  3. Click "Manual Activation" and download the License Request.
  4. Close Unity and connect your internet.
  5. Go to the official Unity Manual Activation Page and upload your Request File.
  6. Download the approved license, it will request you an Unity account.
  7. Unplug again the internet and open Unity on offline mode.
  8. Click "Manual Activation" and upload the Approved License.
  9. Make sure you have now access to Unity on offline mode and close it.

Second problem solved: License activated.

Now you only need to connect again your internet, then open Unity and you will see an activated license without login-in, so you can now log-in with the account you used on step 6.

And now the problem is solved. You have the activated license and you're logged-in.
