After running a few updates through ASDM on the ASA and the ASDM manager, I am now unable to access the ASA through ASDM. I get the error stated in the title after putting in my username and password. Also, when I try to access the ASA through the browser I get an error "404 Not Found" The requested URL /admin/public/index.html was not found on this server. I was able to access the ASA with ASDM without issue before the updates.
I have tried the commands in that thread, with no luck. For the solution on that page it says to run the command "asdm image flash:/asdm.bin". When I run that command I get back "Device Manager image set, but unable to find flash". When I run the command show asdm image I get back disk0:/asdm-792-152.bin. However when I run "asdm image disk0:/asdm-792-152.bin" I get back the same unable to find error.
