Cisco ASA ASDM 404 error

[genccsedanur]

I am getting the following errors while connecting to Asa. I thought that the ASA image file was deleted and I wanted to install it, but none of the commands such as tftp, flash, disk0 can be used. I'm connecting via ssh as I can't connect from ASDM.
I don't understand this problem can anyone help?

Trying for ASDM Version file; url = https://x.x.x.x/admin/
No version file found
Trying for IDM. url=https://x.x.x.x/idm/idm.jnlp/
java.io.IOException: Server returned HTTP response code: 401 for URL: https://x.x.x.x/admin/idm/idm.jnlp/https://x.x.x.x/admin/idm/idm.jnlp/"

Commands were missing when I connected via SSH. I followed the steps when I connected with Console. Thank you.

what is your operating system ?

To see the files that are present on disk0, use the "dir" command.

The boot image is specified with the file indicated in "show run boot". Similarly, "show run asdm" will show the specified ASDM image.
