Can't install anything from opendesktop.org on KDE "SSL hadnshake failed"

I don’t know why, but I can’t install anything from opendesktop.org, using ocs-url or pling-store. I’m not using VPN, but all certificates seems to be invalid.

Unfortunately we could not re-create the error. Are there other users with the same problem?

SSL errors can also be based on an incorrectly set time and date. Could it be because of it?
