Cisco ASA Upgrade issue

Hi Guys,

I have upgraded Cisco ASA 5505 firewall software to 9.1.7.(6) and ASDM 7.6.(1), after upgrade when I've tried to open firewall from ASDM then following error came up:

''This page can’t be displayed Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://192.168.1.1 again. If this error persists, it is possible that this site uses an unsupported protocol. Please contact your site administrator''.

I have tried IE, Chrome and Firefox but still unable to access firewall using ASDM.

Telnet, putty and hyper-terminal connections are fine, Can someone help me to resolve this issue, thanks in advance.

HI SIM50,

Thanks for your quick reply.

The above 3des and aes commands needed activation key to execute the algorithm, I don't understand why it's asking for an activation key as I have got security plus license for this ASA 5505 hardware.

last command ''no ssl encryption des-sha1'' ran ok but still can't access firewall from ASDM.

Regards,
You can get the license key for free from Cisco. Below are the steps.

Enter your CCO userid and password.
Click the “Continue to Product License Activation” link.
Click Get Other Licenses > IPS, Crypto, Other…
Select Security Products > Cisco ASA 3DES/AES License, click Next.
An email will be sent you with the ASA Activation key and instructions on how to apply the key.

After you install the license, rerun those commands for 3des and aes.
Hi SIM50,

Thanks a lot for helping me, your solution worked.
