Cisco Secure Client NAM - Incorrect PSK

[Chris Terry]

We have a user that keeps receiving the error stating an Invalid PSK when connecting to their home network. They are 100% sure they are typing it correctly. The user can connect the first time after adding The network via NAM. If the reboot or connect to the network again (leaving their house and coming back) NAM will throw the Incorrect PSK. They can only connect once and only if they remove the network and add it back. I did notice messages about "Missing PMK"  right before the message is thrown about an Incorrect PSK. 

The user started to see this issue after AnyConnect was upgraded from 4.10.0471 to Secure Client 5.1.2

Cisco Secure Client 5.1.2

TP-Link Deco Mesh Router

In a WPA2 Personal network the PMK is the PSK. The user did state just using the native windows supplicant he does not experience the issue.

NO friend PMK is different and it mostly use for roaming 
you face I think something wrong in wifi

There was another user that is having the same issue. Different home router and different ISP. 

I noticed they both have the same error logs

These message are not related to incorrect PSK.  Is the PSK used something that might have abnormal characters in it?  Do you have a DART bundle with extended logging enabled?

Also, have they tested the latest version of Cisco Secure Client.  Several fixes regarding WPA2/WPA3 compatibility mode went in those releases.

I did have them grab a DART bundle with extended logging. I uploaded that to the TAC case.

No abnormal characters in the PSK and it's under 16 characters. They haven't tested the new version yet.
