Autofirma arroja excepción al iniciar proceso de firma con el Tesoro Público

[wyan]

Desde un Apple Macbook Air M1 (modelo de 2021) con macOS 14.5 Sonoma.

Utilizando Autofirma 1.8.3 desde la página enlazada por el Tesoro Público (https://firmaelectronica.gob.es/Home/Descargas.html)

Intentando firmar el alta de una nueva cuenta del Banco de España para realizar suscripción del Tesoro Público, Autofirma inicia, y pasados unos segundos sin abrir ninguna ventana arroja la siguiente excepción antes de cerrar:

A mí me daba el mismo error y el workaround de este comentario me funcionó (desactivar que solo permita conectarse a sitios seguros) #321 (comment) .

[wyan]

En ese caso casi que prefiero mantener mi solución actual (usar una versión anterior de AutoFirma). Desactivar la seguridad me parece una opción francamente preocupante...
