Yeah, unfortunately that is often what's required.

Probably driver differences between Windows and Linux that trigger that
bug in the AP.  And the Android phone probably has different wifi
hardware that wouldn't have that issue.

That's a great question, and it shouldn't take that long.  Can you grab
supplicant debugging for that?  Run these two commands:

sudo dbus-send --system --print-reply --dest=fi.w1.wpa_supplicant1
/fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Set
string:fi.w1.wpa_supplicant1 string:DebugTimestamp variant:boolean:true

sudo dbus-send --system --print-reply --dest=fi.w1.wpa_supplicant1
/fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Set
string:fi.w1.wpa_supplicant1 string:DebugLevel variant:string:"msgdump"

(yeah I know they're long) and then you should have lots of debugging
info in your logs for the supplicant process.  Note this may disclose
your passphrase, so you might want to take a look first and scrub them.
