Cannot connect to the ASA 5506-X Firewall

Andrew5245
Level 1
Level 1

Hello, 

I am having trouble accessing my ASA 5506-X through the ASDM Launcher. "Error : Enable to launch device manager at 192.168.1.1"

When i try to access through Google chrome i get this error :

"Unsupported protocol
The client and server don't support a common SSL protocol version or cipher suite."
So i tried changing the SSL client-version to "any" but another error occurs :

I am also trying to change the IP address but no luck :

2019-11-14 12_03_20-COM7 - PuTTY.png

I did some research and some of the discussion said to set a username and password. So i did that, but still no luck 

I have also tried :

Some help would really be appreciated 

Regards, Andrew.

PS : This firewall is brand new with factory default configuration.

Thank you for your help.

I found a solution to the problem in the end

I activated the 3DES/AES licence that comes with the control licence

 - Try : ssl encryption rc4-sha1 aes128-sha1 aes256-sha1 3des-sha1

    Actually that came from a more general trouble shooting document  on ASDM which you may want to review :           https://community.cisco.com/t5/security-documents/asdm-access-troubleshooting/ta-p/3122148

Once again an error :

 - Use : 

        ciscoasa (config) # ssl encryption ?

 to get a list of available ciphers.
