I can reproduce this on OpenSUSE Tumbleweed.
Sounds like a downstream problem
Comment 3 Fabian Vogt 2021-06-18 08:54:39 UTC
Already fixed: https://bugzilla.opensuse.org/show_bug.cgi?id=1187457
Comment 4 Nicolas Fella 2021-06-18 08:57:39 UTC
Can confirm that installing qca-qt5 fixes it. Thanks Fabian and Christophe
Comment 5 Cristiano Guadagnino 2021-06-18 09:07:28 UTC
After installing qca-qt5 and restarting kdeconnectd I do not have anymore the message "Could not find support for RSA in your QCA installation", but I still have the "key not valid" message:

kdeconnect.core: Private key from "/home/cristiano/.config/kdeconnect/privateKey.pem" is not valid
kdeconnect.core: LanLinkProvider/newConnection: Host timed out without sending any identity. QHostAddress("::ffff:192.168.178.100")

Here is the situation with my qca-related installed packages:
