SSH Access Internal Error (0x00)

[4kalak4]

Hi friends!

I'm trying to access from my "OpenSSH Client" (OpenSSH_7.9p1) to my "FirePower-2140" via "SSH".

However, "FirePower" refuse the connection with an error "Internal error (0x00)".

The attached image is the debug output from my "OpenSSH Client".

The attached txt file is the output of the "debug ssh 255" from my "FirePower-2140".

What could be the problem?

  - For reference  try with another ssh client , such as from linux (ssh) and try verbose mode. 2) Check the firepower's ssh related logs  , btw : despite references to attachments , there are no attachments in your post  ,

Hi sotog24726,

I created a new RSA key.

However, I obtain the same error.

Hi friends!

After create a new RSA Key in my "FirePower-2140" and change "ssh key-exchange hostkey ecdsa" to "ssh key-exchange hostkey rsa" access to SSH works correctly.

However, if I change "ssh key-exchange hostkey rsa" to "ssh key-exchange hostkey ecdsa" access to SSH fails again.

Any ideas?
