Product: Zoo
Summary: What to do when returning a license validation fails

If you got to this page, you're likely trying to remove a license from LAN Zoo and got this error message:

Your license cannot be deleted because the McNeel license server at https://api.mcneel.com could not be reached

This message is shown when LAN Zoo is able to access parts of the Internet, but cannot access McNeel's license servers at https://api.mcneel.com

To Resolve The Error:

1. Verify that a local or network firewall is not blocking port 443 access to the server api.mcneel.com
2. Try to remove the license again.

If License Removal Still Fails:
