Unable to access ASDM on ASA5510

upper
Level 1
Level 1

We have now been unable to access the ASDM on our HA Pair 5510's from any of your previously working Windows 10 PC's.  If we try via the ASDM client we get the error "unable to launch device manager" and if we try and launch thru IE we get error below

com.sun.deploy.net.FailedDownloadException: Unable to load resource: https://75.150.146.201/admin/public/asdm.jnlp

Here is the output of sh run all ssl command

GuthrieRoadFW# sh run all ssl
ssl server-version tlsv1
ssl client-version tlsv1-only
ssl encryption aes256-sha1 des-sha1 3des-sha1
ssl certificate-authentication fca-timeout 2

 

we have tried rebooting the each of the 5510's and have not been able to get this to work. SSH works just fine and we have the http server enabled and all subnet are configured correctly

 

Any help would be appreciated

@upper 

Are you permitting http access from the outside interface? e.g.

http x.x.x.x x.x.x.x OUTSIDE

 Try enabling server version TLS 1.1 or 1.2 (if your ASA version supports it).
