Error Trying to connect to SSH to an FTD reimage to ASA

[Alemend88]

Hi guys could someone give me a hand on the following error that Im getting from the device, this is a FTD 2130 but it was reimage to ASA 9.8(4)25, below is the current config 

crypto key generate rsa modulus 2048

username **** password ***** priv 15

aaa authentication ssh console LOCAL
 ssh 0.0.0.0 0.0.0.0 management

ssh timeout 5
ssh version 2
ssh key-exchange group dh-group14-sha1

ssh -l user x.x.x.x 
[Connection to x.x.x.x aborted: error status 0]

Im able to ping the device and acces to it via telnet(which I will disable) however ssh its not working. Please let me know if Im missing something

is this working before upgrade ? if it was working - regenreate crypto RSA Key and try again.

if it was not work ever, then post your configuration to look.

Hi,

try removing the command 'ssh key-exchange group dh-group14-sha1'. Your ssh
client might not support dh group 14. Just use the default dh group,
regenerate the key and see if it works.

Hi guys thank you very much for your answers,  I ran a debug ssh and found out that  AES or 3 DES encryption algorithm are not available, so I have a problem with the license, right now I have a ticket with TAC since they still have my license as a smart one.

sho ver | i AES
Encryption-3DES-AES : Disabled

Thanks a lot for the help

You can get a license from the licensing portal, without having to go via TAC.
Go to your Smart Account, then Get Licenses, then IPS, Crypto or Other
Select Security Products, then Cisco ASA 3DES/AES License
