How can I restore old session keys about lorawan-server HOT 1 CLOSED

I was able to solve the problem, I found the AppNonce value issued with the given datum, which I used to restore the session keys.
Because in the meantime I found out that it is not stored in the database by the lorawan server, but logged in a "debug.log" log file.
The only problem was that the server had deleted the debug.log file a long time ago, because it only stored 5 log files on top of the current day.
After that I was just lucky that I could restore the file using the Linux server recovery operation, and in the meantime the server did not overwrite the next log entry:
2023-08-10 14:43:36.520 [info] <0.10317.23> device ...{join,<<"00...A">>}
2023-08-10 14:43:36.521 [debug] <0.10317.23>@lorawan_mac:encode_accept:441 Join-Accept <<"00...A">>, netid <<0,0,0>>, cflist undefined, rx1droff 0, rx2dr 0, appkey <<"9...93">>, appnce <<"58C822">>
I had searched for "appnonce" in the debug.log file earlier, but couldn't find it, now I know it's because it's misspelled "appnce".
Please correct the typo when you can so that it doesn't cause problems for others.
