software upadtes and add-ons problem

I tried to update Knime and install Weka nodes but after opening the
"software updates and add-ons" box, I get this message:

“No repository found at
Error reading update site
Connection refused: connect”

Any idea how to get around this problem and install Weka?

This error message often happens if your are behind a firewall or need a proxy for connecting to the internet. What happens if you enter the URL in your browser?

I think you’re right because I get the message saying “forbidden” if I enter the url in my browser.

However, I was able to open and download the alternative link with zip files and install the files from my hard drive instead.

Now it’s working :slight_smile:

Thanks for your help !
