Issue with LND after Raspberry reset

Helle there

Few days ago I had an issue on my Raspberry Pi 5 which forced me to reinstall everything from scratch.

The issue now is that to recover my funds on Alby Hub I need to backup the LND channel and since I did not know GetAlby was usining the LND service I did not backup this last one.

Alby support told me to contact the support here because you may have this backup file stored but I am not sure if it can be possible as in fact I do not have an Umbrel device.

Thank you in advance!
