I had ASDM access on my 5510 ASA before configuring the device for anyconnect VPN access. After successfully getting the VPN working, I get a "cannot open device" error when attempting to connect into it from my existing ASDM software. When I navigate into the device via the inside interface address, I can get to the page where you can download the ASDM client or run as a java app, but it never lets me connect all the way in, I get a "cannot open device" error. Also odd but potentially unimportant, the ASDM version on the inside interface address shows the wrong version of the ASDM software. This is odd because there's only one image of the ASDM software on the device, and it's not that version.
I'm comparing this to a working 5520 config and I cannot find the issue. Attached is the sanitized config. Any help is appreciated. Either in the form of config modifications or what I can turn on debugging wise to troubleshoot this issue.
