Loading of providers from file: https://autoconfig.kde.org/ocs/providers.xml failed

how can I solve?

Are you connecting through a proxy?

There is a known problem with “Get New Stuff”, “Get New Widgets” etc… See: https://bugs.kde.org/show_bug.cgi?id=447281

…and as I understood no workaround or solution:|

It appears not at the moment, the various developers are “discussing” the issue…

You could perhaps look around the “KDE Store” https://store.kde.org/browse/ and download directly from there.
