Contacting software sites error when I try to update Knime or find an extension

Hi guys,

I face this error when trying to update Knime or find an extension:

It happened with version 4.3 and again with the 4.4.

Do you know the reason and how to fix it?



Can it be the content file is corrupted?

I’m opening a ticket for it and I will let you know.
