I am currently unable to connect from my Pi 4 w/- Pi OS (buster) to a hotspot on a Ubuntu MATE 20.04 machine (laptop).
The Ubuntu MATE hotspot was set up with a WPA/WPA2 passphrase; using the desktop connection manager.
I have been able to connect to the Ubuntu MATE 20.04 hotspot from my Android device.
The hotspot is visible to the Pi OS. However, when I enter the passphrase, I merely get a popup error saying the network could not be reconfigured.
I am also able to connect to other hotspots with my Pi 4.
Any help with debugging this or solving this would be greatly appreciated.
