Trouble connecting ASDM to Firewall

W425
Level 1
Level 1

Attempting to configure a ASA 5506 using ASDM, and am able to connect with one PC to the ASA using ASDM but using ASDM on a different PC, I get an error that unable to connect to the ASA firewall.  It appears to be related to the ASA Firepower, as I when I connect directly to the ASA5506 on port 1/2 (and disconnected from the Firepower on the mgmt. port 1/1), the ASDM connects OK (but obviously not to the Firepower).  Note, this is the ASA 5506 version 9.6 which requires a switch connecting port 1/2, mgmt. 1/1, and the PC.  I have checked about every configuration that I can think of to ensure that the configs match between PCs.  I could use some ideas as to what configuration or difference between the PCs would allow one to connect but not the other.

hi,

is the other PC's IP or subnet range is on the allowed list for HTTP? can the other PC and ASA MGMT IP ping each other?

http <OTHER PC IP/SUBNET> <SM> management   

 

check the java version on the 'working' PC or check via ASDM by going to Help > About Cisco ASDM. see attached pic. mine's using ASDM 7.8(1) and Java 1.8.0_131.
