What is the problem?
Brand new install from 2019-09-26-octopi-buster-lite-0.17.0 . Burn to sd card, modify my supplicant for the network. Wifi doesn't work. Plug card into network powered by an Amazon 9W PSU, get IP, but can't SSH in or goto webpage, get 500 internal server error.
What did you already try to solve it?
Reflashed SD card multiple times. Different PSUs. Different network cables.
