I tried this on Mac and Win10 using different browsers and different JRE versions, result is the same.

Could you please help?

Thanks!

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.
