Hi,
I have generated 63-characters WiFi password for all devices in my house, so I can't really change it just for RPi.
For some reason, I can't set it in connman config either - get "invalid-key" error.
I also tried to convert the password to 64 digit with wpa_passphrase, no luck.
Both methods work in connman on Ubuntu (version 1.36 vs 1.39 on LE).
If I temporary change the password to a fake 12345678, then it works on RPi.
Could someone confirm the problem, at least? I'm on LE 10.0.1 for RPi4.
