"Error uploading license" displays on Advanced Threat Protection when registering the appliance

When registering the ATP appliance, you are asked to upload the license file. After selecting the file, you see:

Error uploading license


This indicates a communication issue when trying to upload the file to our licensing servers.


  1. Verify that the ATP appliance has access to the licensing servers; the Cynic license server [] and the Aztec server [] by using the 'status_check' command at the console.
  2. If status_check indicates EDR fails to access one or more servers, check unencrypted tcp connectivity more closely using tcp_check -t [server] -p 443
  3. If tcp_check shows errors, resolve before continuing.
  4. If tcp_check -t shows no errors, use tcp_check -s [server] -p 443 to check for issues specific to encrypted tcp traffic.
