ASDM not working with ASA 8.4

[central_bank]

                   hi

I have recently upgraded ASA to 8.4 and found that ASDM is not working on it. I tried the latest ASDM version 7.1 still no luck.

When I try to access ASA using IE...it just shows " Page can not be displayed "

Following is the config which I have

http server enable

http 0.0.0.0 0.0.0.0 inside

http 10.52.193.218 255.255.255.255 inside

asdm image disk0:/asdm-711-52.bin

asdm location 0.0.0.0 0.0.0.0 inside

asdm history enable

Is there anything else required in ASA 8.4 for ASDM to work?

When I telnet to ASA interface with 443 port it works

I have noticed the same problem ...

Probably the java (wich is used by asdm) installed on your management PC doesn't suppport legacy versions of SSL and weak cryptography (like DES) for communicating with ASA. Maybe ssl-encryption in your config is set to des? If so, then change it to smth more appropriate (3des, aes).

No, that seem not causing the problem, I have got more ASAs to manage. I got 2 new delivered who caused the mentioned problem.  I looked for more causes but no solution.

If you already have ADSM-IDM launcher installed on your system then try to open with that.

of course

My new ASA is a ASA5545-X

I installed different means a older ASA Version and I tried several ASDM Versions. Nothing happens, the ASDM isnot working, even with the factory default on Management Interface it will not work.

I checked it with https://supportforums.cisco.com/docs/DOC-15016 and find out that following was missing:

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

After that it runs.

Isn't it exactly what i said before?

Andrew, Yes, but I except from Cisco thank they may be able to deliver an simple running config that work on there boxes. If i have to find out first by cli why something isnot working. Therefore a :-( for Cisco and a .-) for Andrew
