The PSK based authentication refers to the shared key between the VC and Airwave:

In Airwave you can check/change that on the VC. But as far as I know, if you manually approved/imported the APs in Airwave, it should not be needed; the secret is mainly used for automated onboarding of APs in Airwave.
One thing you should probably verify is if your Airwave version is new enough to support the 8.10.x AP firmware.
If this doesn't help, reaching out to your Aruba partner or TAC may provide a faster resolution.
