Upgraded ASA, lost ASDM

[zietgiestt]

Hello,

I just upgraded my ASA 5516x HA pair firewalls from 9.8>9.16.

Upgrade went fine and everything seems to be working as it should.

Replication completed successfully, failover status is good, vpn tunnels are connected.

Before the upgrade I copied a new asdm .bin file (7.16.1), but I can't download it from a web browser. 
I can't even reach the download page.
I can ssh into my primary and secondary firewall.

http server is enabled with a specified port, but I get a 404 error. 

My older version ASDM isn't compatible with the new ASA software so I get an error of "unable to launch device manager from https://

I'm unsure what happened to my https access???

Any help is appreciated.

Thanks,

check the compatibility matrix : ( you mentioned 9.16 (what is after that X?)

https://www.cisco.com/c/en/us/td/docs/security/asa/compatibility/asamatrx.html#reference_upj_nkl_x4b

try clearing the browser cache or try other browsers.

check other options :

#show asdm image 

check one of the suggest made in the forum :

no aaa authentication http console LOCAL

Thanks for the reply...I guess I read the matrix wrong and was trying to use an incompatible ASDM version. 

I tftp'd a newer version (7.20) and after installing a new version of java, I'm in. 

appreciate the response.

Please share "show run http" and confirm the source address you are coming from and which ASA address you are going to.

You might also try temporarily returning to the default http(s) port (443).
