Hmm, option B is interesting too. Maybe there's a need to explicitly specify the port in the package_config.ini file. It's always good to check multiple config files when troubleshooting these kinds of issues.

You know, I was just reading about Mosquitto the other day. It's a really popular MQTT broker, so this issue is probably something a lot of people run into. I wonder if there's a typo in the config file or something like that.

Hmm, this is an interesting problem. The error code 5 usually indicates a connection refused, which could mean a firewall or port issue. I'm thinking the solution might be related to the ports or network configuration on the Cisco router.
