Re: [mosquitto-dev] Connections refused in mosquitto 1.4.2 on raspian

[Roger Light <roger@xxxxxxxxxx>]

Hi Bernd,

Have you tried connecting with another tool, e.g. mosquitto_sub? Please try from the same machine you are attempting to connect from and with the same host/ip address.

Cheers,

Roger

First a start log output of mosquitto:

pi@raspberrypi ~ $ sudo mosquitto -v -c /etc/mosquitto/mosquitto.conf

1433677377: Opening ipv4 listen socket on port 8883.

Second a netstat -lnp

I am not using TLS as far as I know.

Does this help?
