Could you please help?

Re: ASA ASDM Not working

Your ASA may have been ordered with the "K8" part number meaning it does not have the free 3DES-AES license. Without that, it will not be able to negotiate a sufficiently secure SSL/TLS connection to be accepted by your browser.

 

You can check from the cli with the following command:

 

show ver | i 3DES

 

If the license is not active, you can get one from software.cisco.com via self-service.
