Which AP are you using?

You have configured to client to use only CCMP.

However, this debug log shows following:

WPA: Unsupported CCMP Group Cipher key length 32 (32).

In other words, it looks like the AP tries to use TKIP as the group
cipher. Either wpa_supplicant configuration would need to be changed to
accept TKIP as the group cipher or the AP configuration would need to be
changed to use CCMP as the group cipher.
