inverter_scan.py PermissonError: Permission denied

[joysfera]

Hi there,

when I run the inverter_scan.py I get Permission denied. Tried running it also under root - didn't help. Tried modifying the broadcast IP address from 255.255.255.255 to 192.168.1.255 (my LAN is 192.168.1.0/24) - didn't help either. Any idea how to get the scanning working, please?

Oh, the OS is Debian based (DietPi v9.8).
