I'm been following this thread but it looks like its not a problem of Ledger Nano S but the OP has been scammed:
This is indeed a scam I lost 24ETH today because of this stupid hardfork. Be careful about it guys.
His been a victim and I'm sure lots of users as well, so just beware of this stupid hard fork or something. Reminds me of what had happened during the bitcoin fork as well, a lot of videos and help going around, even someone development this so called wallet to claim your free bitcoin cash but it turns out to be scam as well.
Learning from the forum will help the people to avoid scamming and claim their forked free coins in the best way,there are really some good experts are helping at the technical queries so follow the other sections as well to get complete knowledge about everything related to crypto.
