Ich baue ein Projekt mit Laravel. Auf localhost hat es einwandfrei funktioniert, aber wenn ich es auf den Server hochlade (auf dem Server ist comodo ssl installiert), wird folgende Fehlermeldung angezeigt:
RuntimeException in EncryptionServiceProvider.php line 29:

Kann jemand helfen, diesen Fehler zu beheben?
