thanks for the traces. so I switched to networkmanager as well, and it still works here just fine.
however, I found this which describes the same issue, also with status_code=0x40 rejection:
it looks like a defect on the fritzbox side according to the analysis there, where WPA2+WPA3 transitional mode is not working as the AP is not indicating it needs 11W, while it refused to connect without it.
I've switched to wicked service instead of networkmanager and the problem is gone even with the 2.10 (standard version) wpa_supplicant
Issue in Networkmanager instead?
