Empty /boot/octopi-wpa-supplicant.txt

All working fine, did sudo apt-get update and sudo apt-get upgrade on my setup. Shutdown, power off, restart. No Octopi connection.

Opened /boot/octopi-wpa-supplicant.txt and it is empty.

Where can I get that to reconfigure?

No idea where it went...

go look at /etc/wpa_supplicant/wpa_supplicant.conf
Octopi sets it as a link to the .txt file in /boot. Possibly something in the upgrade removed the link and wrote the empty file instead
