Problems backing up Cisco-Switch Configs

Hello

I'm currently evaluating DeviceExpert. It works fine for all of our Cisco Routers. I can however not get the config-backup feature to work with our Cisco switches. When I backup, I see these Messages in the serverout0.txt:

and so on. tcpdump output of the session looks like this:

Backing up from this switch to a different tftp server on the same local network works fine.

Is there anything I can do to get this running?

Thank you and kind regards
