Current Behavior

I cant seem to send Robot programs to UR-Robots (CB3 Polyscope 3.15) with the FTP option. It works with UR-sim with the ip input: sftp://ur:easybot@IP/home/ur/ursim-current/programs. It does not work on a real robot with sftp://IP as well as with any directory or with added username and password(root:easybot). The remote connection LOG-output tells me: ERROR: FTP - the method or operation is not implemented.

I can connect to the robots ftp-server via Filezilla without problem. What could I be missing? Why is there a difference between Polyscope 3.15 on URSim and a real Robot? Where does the error “not implemented” come from? is this part of the plugin or some C# Library. Could it be specific to MacOs? Thanks for any advice

In this image you can see the output of the remote connection Log. The first 2 items are with the real robot the third item is from a connection to URsim

This new .dll file works on my 2021 Macbook! Thank you very much, this will make working with larger files so much easier.

Thanks @robin-gdwl, It seems to be due to mono (used on MacOS) not implementing certain cryptographic algorithms. I’ve followed a workaround mentioned here. Here’s an updated Robots.dll file that you can test containing the workaround: Robots.zip
