Unable to launch Device Manager - ASDM issue

Hi There,

I have recently upgraded our spare ASA 5510 router to version 9.1(3) with ASDM image Version 7.1(5)100.

The client i'm attempting to run the ASDM launcher on is Windows 7 x64 running the latest version of Java (7 update 5).

I am able to get to the main screen when I https to the device.  I can install the ASDM launcher, but once I enter the hostname and Password I receive the following error "Unable to launch Device Manager 192.168.X.XXX".

I have gone through a check list and I can confirm the following:

- the 3des-sha1 licence is enabled

- Http server is enabled for my clients subnet

- ssl encryption is enabled

- Tried Firefox and IE10

When I attempt to run the ASDM via the browser I get as far as asking for the password and although the initial prompt seems to accept it, another authentication box appears asking for it over and over again in an endless loop.

I have been through many forum posts and check lists, but cannot seem to pinpoint this problem.

If it helps, the box was previously flashed back to factory-default before I then applied the configuration from scratch (based on the config of our live ASA 5510).

Can somebody help please?

Thanks

Hi Anthony,

I had this same issue. I resolved it by opening Java (Windows - Control Panel Java - Select Security Tab Select Manage Certificates. Select Certificate Type and choose Secure Site) on a known working ASDM installed computer.

Export the "Trusted Site" cert and import it on the computer with ASDM issue.

This resolved the issue for me.  I exported the self-signed certificates from each of my ASAs and then imported them into the "secure site" section in Java console (the "trusted certificates" section did not work).  I have seen this previously for another java application as well.  This was with ASDM 7.1(5)100 and Java version 7 update 51.

@ Joel Asaro:

thanks man. you saved my day...
