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.
