ASDM Fails after upgrade with error: "Unable to launch device manager"

[gcarleton1]

I upgraded by ASA 5525x with asa9.14.4 which is a special version for a security fix.   That broke ASDM.  So, after consulting my Cisco Field Engineer I upgraded ASDM to asdm-7.23.1.  After updating the path and upgrading Java to the recommeded version I get this error..."Unable to launch device manager from x.x.x.x:65000 (which is the interface I have launched it from for the past 11 years).

When launching the app it acts as if it is find giving the connecting to device message.  Then is stops and displays this error message.

Any suggestion of what is actually  going on would be appreciated.

First, double check your running-config via cli to verify the http server is still enabled. I have seen that comm,and "disappear" once or twice during upgrades. Also verify the non-standard port number is still in place. If that checks out, then check your Java console during the connection attempt. It sometimes gives clues by throwing errors about TLS versions and/or certificate non-acceptance.
