Issue with downloading knime extensions


I am trying to update my knime with extensions to enable extra nodes like remove duplicates. But i am constantly running into the following error. Did anyone experienced the same? Any resolution ideas?

It looks like you have an unstable internet connection and the downloaded files are corrupted after they have been downloaded. You can try to download the a zipped update site and install from there.
