ASDM ASA 5525 Error

[majid3612]

I have recently updated Java to latest version as well as ASDM software version to 7.14. Afterwards, I cannot connect to ASA using ASDM due to the error message attached. The following is some parts of call stack in Java console:

I added ASA certificate to Java as well but I still get the same error. 

Any solutions?

The error mentions "Trying for IDM." That's the old IPS Device Manager (long past end of life). Does your ASA have an IPS module by any change?

I also notice you are using a custom port for ASDM (11443). Has that always been the case?

[majid3612]

My ASA has IPS (Firepower). The custom port (11443) doesn't cause the issue since it was fine prior to upgrading to version 7.14. What's your recommendation?

[Marvin Rhoads]

That's odd.

I am using ASDM 7.14(1) to access several different ASAs. I am running Java 8 Update 271.
