Problem beim Start von MediathekView auf MacOS

[Helfried]

Ich habe im Forum nichts zu meinem Problem gefunden, daher stelle ich es mal hier rein.
Seit ein paar Wochen funktioniert MediathekView (13.6.0) bei mir nicht mehr richtig - ich bekomme beim Start neuerdings immer die Meldung “Netzwerkfehler aufgetreten” und die Liste wird nicht vollständig aktualisiert. (Der gesamte Fehlertext steht unten).

Ich benutze MacOS 10.14.6 Mojave. Der Versuch, ältere Versionen
(13.5.1, 13.3.0) zu starten, führt leider auch zu derselben Fehlermeldung.
Java ist auf dem neuesten Stand, und ich habe nichts an meiner Konfiguration in de letzten Monaten geändert. Hat jemand vielleicht eine Erklärung, bzw. ein ähnliches Problem ?

Vielen Dank
Hel

Nutzt du evtl. Kaspersky oder andere Tools die versuchen an der SSL Verbindung “Rumzupfuschen”?
