Ich versuche mit Yesod's cookbook for a blog zu folgen. Ich habe ein paar Dinge geändert, wie den Wechsel zu einer PostgreSQL-Datenbank, das Hinzufügen eines Links für die Google E-Mail-Authentifizierung und das Verschieben einiger Shakespeare-Vorlagen in separate Dateien.Warum wirft meine Yesod-App eine TlsNotSupported-Ausnahme, wenn ich mich anmelde?
Mein Problem ist, dass, wenn ich die App laufen und versuchen, zu authentifizieren, bekomme ich eine TlsNotSupported
Ausnahme zurück und ich habe keine Ahnung, was es verursacht oder wie es herauszufinden. Ich habe beide Formen der Authentifizierung in einer separaten App verwendet und beide haben gut funktioniert.
Mein Code ist unten. Jede Hilfe würde sehr geschätzt werden.
