Electrum_LedgerNS_Issue, is there any new information regarding your case? I see that the problematic transaction is still intact/unspent which can be a good sign (if it is not in the classical hack), which means that there is still hope for a solution.
I have something similar in past when I play with change address from Ledger, and one transaction was invisible because Ledger Chrome app was set to not check all addresses. I fix that in Electrum with increasing the gap limit. If only the solution would be so easy in your case...
Hi Lucius,
Unfortunately nothing new for now. I've generated about 50m addresses from my mnemonic seed by now on the derivation ranges I thought probable, but no luck so far.
I'm pretty much trying to understand what happened at this point, can't do much without knowing what went wrong, generating addresses is a shot in the dark.
I guess I'll need to get the help of a digital forensic and try to find a trace of the receiving address on my machine.
