Connectrix B-Series: TruFOS License install failed - Failed to copy the file from the remote location using SANnav UI.

Entering a command to import a license or TruFOS XML file in the following format is failing with the error message "License install failed - Failed to copy the file from the remote location":

license --install -h <IPaddress> -t <protocol> -u <user> -p <password> -f <filepath>

However performing a configuration backup to the same file transfer server with the same user account (using the configupload command) is working.

This can occur if there is a special character like an exclamation mark or bracket in the password for the user on the file transfer server.

Fix:
Install the TruFOS license interactively using the CLI.

(The -p <password> segment from the license installation command is the only interactive argument of the command using CLI. When entering the license installation command without the -p <password> segment, you are prompted to manually enter the password. Here you can enter the same password (with the special characters), but it is accepted.)
