I upgraded the BIN files of both the ASDM and the ASA image.
Everything seems to be good, I can access it via SSH and login no problem.
Went from ASDM-523 to ASDM-615 and ASA-723 to ASA-804...
I cannot access the ASA via HTTPS or ASDM manager as a box comes up and asks me to select a certificate to be used for authentication from the list, but there is none there...
How do I fix this?
