KDE cannot download any themes - SSL Error?

Hi,
I have issue getting any new Global themes and similar stuff (task switcher etc). When I hit “Get New Global Themes” I got:

  • An Error Occured - Loading of providers from file: autoconfig. kde. org /ocs/providers.xml failed

When I run it from console I can see on the last line: kf.newstuff.core: “SSL handshake failed”

Since Lets Encrypt Certificate exipred I got sometimes similar issues playing videos via FreeTube - I got Kde Plasma pop up saying issues with certificate (when playing from specific FreeTube instances).

I tried loading new Lets Encrypt Certificate (DST Root CA X3) and disable expired one, but still same issue.

Thanks a lot for any help
