Cant connect from management port to asdm web interface asa5520 F/W

[JodyPetroni]

Hi Community

I am trying to connect to the ASDM web interface from a PC connected directly to the management port of the ASA5520.

Below is the configuration: -

1. asdm

2. Management Interface

3. http Server

4. On the PC I have connected a cat6 ethernet cable directly to the management port on the FW. I have given a static IP address of 192.168.5.100. I can ping 192.168.5.1 but I get this

whats going on? what have I missed?

thanks

I feel as though its something to do with the TLS version on the ASA FW

first let check the compatibility.
check link above for compatibility between ASDM and ASA ver. 

share the following 

ASAa# show run all ssl
