Can't get ASDM to load on ASA 5505 after upgrade...

So I was switching a client over from a T1 connection to cable this past Saturday and ran into a problem. What would have normally taken me no more than a half hour I decided to update the ASA from 7.2.5 to 8.2.5 and the ASDM from 5.2.5 to 7.15.100. This ASA is an older model and only shipped with 256m so I need to keep the ASA under 8.3.

I changed the boot image to boot to 8.2.5 and everything booted as expected. I then changed the ASDM to use the 7.15.100 image and for the life of me I couldn’t get the ASDM to load. I then decided to clear the config and start the ASA fresh and build a new config and still can’t get the ASDM to load.

So right now I have an ASA with only an ip address on the inside interface and I have all the lines needed for the ASDM to load:

asdm image disk0:/asdm-715-100.bin
http server enabled
http 192.168.1.0 255.255.255.0 inside

There really isn’t anything else in the config b/c I reset it back to default settings… It is also not a Java version on my pc b/c I can connect to other ASA’s with no problem and I am still running ver7 update 46.

Anyone have any ideas for me to try?
Thanks,

What version of Java are you running?  This sounds a lot like a java issue.  You may want to try either upgrading or perhaps even downgrading (if you are running the latest version of java) Java and then test

I can assure you that is isn't java. I just looked and I am running version 7 update 45.

All the problems with ASDM as of late are due to update 51.

Are you seeing any error message when connecting with Java, or is it just timing out?

Are you trying to connect with your existing ASDM application that is already installed on your PC?  If so I suggest uninstalling that and then connect to the ASA to download a new copy and see if that helps.

Hello everyone, after many frustrating hours I finally figured out my own issue. I had to issue the following command to get everything working:

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

Looks like for some reason the device didn't have the ssl encryption enabled for the asdm to work. Thank you all for you help.
