I am looking for any information regarding the following issues after upgrading.
My customer has upgraded their ASA 5545-X to 9.1.2 interim from 9.1.2, ever since doing that, neither the management port or the VPN functionality are usable anymore. degrading to the initial 9.1.2 works fine.he compared both configurations and they are identical, except for different ordering, which shouldn't be relevant.
he replicated the error by upgrading it to 91.2.interim, with the same result.
When accessed by browser, the management port only displays "401 Unauthorized", rather than showing the ASDM download page.
The logs don't contain any helpful information, but show that the TCP connection and SSL handshake are completed successfully.
Upgrading from ADSM 7.1.2 to 7.1.3 didint help either (7.1.3 hangs in some places, so it wouldn't be an acceptable workaround either).
When turning on HTTP debugging, the following lines are displayed on the console:
HTTP: session verified = 
HTTP: processing GET URL '/admin/public/asdm.jnlp' from host [...]
Is this a known issue with the latest release?
What debug commands could provide useful information (aaa, acl, webvpn, ...) either there are no output or no nothing useful.
PS: on Cisco BUG tool, I didn't even see 9.1.2 as version displayed
thanks in advance
