Problem Details: Cisco Application Deployment Engine OS Release: 3.2 ADE-OS Build Version: 3.2.0.401 ADE-OS System Architecture: x86_64 Unable to add repository to ISE deployment error message showing want to upgrade from 3.2 > 3.3

I am able to ping the repo server from the ISE GUI and I have made sure the username and password are correct several times..

You have tried/guessed all sorts of protocols for the same IP - what protocol(s) exactly does your remote server support?

Sometimes the issue is the filepath, depending on how the remote server handles the home directory - e.g. if it's a linux FTP server, and the username is ftupuser, then the ftpuser home account might be /home/ftpuser - but the FTP server might have assigned that account to /opt/ftp/ftpuser or whatever. It might also 'jail' (chroot) the user to a virtual / (root) directory, so that the user cannot get out of that path.

I would do the following

• Test the username/password with a non-ISE client (e.g. WinSCP), or another linux host
• Debug the process in ISE on the CLI

  debug transfer 7
  show repo isebackup

• Maybe there is a firewall blocking FTP and/or other protocols from ISE to the remote server. If the server supports SSH, then try logging into the server from ISE CLI using ssh command.
• Advisable not to use FTP as a long-term solution since the protocols is ancient and insecure - your backups are encrypted (that's ok) but your username/password is sent in cleartext
