Evita que podamos levantar el servicio de mosquitto, debido a que nos exigue TLS habilitado, pero para pequeñas pruebas en local podemos comentar la linea siguiente:

grep -n cafile /usr/local/etc/mosquitto/mosquitto.conf

282:# cafile, certfile, keyfile, ciphers, and ciphers_tls13 options are supported.
354:# cafile and capath define methods of accessing the PEM encoded
357:# cafile defines the path to a file containing the CA certificates.
363:cafile /usr/local/share/certs/ca-root-nss.crt (1)
844:# Either bridge_cafile or bridge_capath must be defined to enable TLS support
846:# bridge_cafile defines the path to a file containing the
853:#bridge_cafile

1	La linea 362 la comentaremos.
