When I gave up trying to get the Ledger to show my account balance .( it showed zero balance),I downloaded Electrum ,at the advise of someone on this forum.
That was super easy , but Electrum showed zero balance too .
And electrum wallet is full sync? If yes, you should wallet transaction details which will show you when the coin was moved.
I live alone and know one had my seed or private key ,or password to my Ledger.
Living alone doesn't make less vulnerable to attack if you can avoid the basic human error and the last time I checked most Nano S user lost their coin through buying their wallet from an unofficial store, human error and chrome Ledger extensions. As said early the device needs to be accessed physically for it to get hack, if you truly lost your coin then someone has the private information to access the wallet.
