Good Day,

I have asa 5505 on which i would like to access asdm. when i try https://x.x.x.x , it doesnt launch asdm , however it goes and prompts me to enter username and password

i can do telnet to asa from one of the server machines which i have allowed on the asa. login to enable mode and do whatever changes required.

i have http enable
           http inside

on the asa , when i do sh run.

apart from that not sure what else to. it used to work before. appreciate assistance.

while its prompting username password, you need to provide username and password.

Once the password is right, you can see an option to download ASDM

there is no user. all i get is prompt for passwords and thats it. last time , we had disabled no transport input all. not sure if that has got anything to do with it,tried creating a user with priv 15 level. it still doesnt login and shows invalid login .
