Can not connect ledger to claim spark

[Gloria]

Hello, I need help. I can not connect my ledger to set up message key to claim spark. What am I doing wrong? I tried different laptops with  same windows 10, but still no lock. I even have to removed my antivirus, but still did not connect. My nano s firmware has the latest version 1.6.1.

Can you give more detail about that problem you're having? Any error messages you're getting?

When you say "connect", do you mean you can't even see the Nano in Ledger Live, or the online Spark claim tool?
