Neolink does not connect to MQTT broker. WARN: Connection Lost: Dropped connection

[Bagunda]

Describe the bug MQTT is not working. Just downloaded a fresh file for today's date. Both Home Assistant and MQTT broker are updated to the current version.

To Reproduce Steps to reproduce the behavior. Example:

1. Create this configuration file:

bind = "10.2.90.202"
bind_port = 8555

[mqtt]
broker_addr = "10.2.90.8"
port = 1883
credentials = ["superuser", "superpass"]

[[cameras]]
name = "ArgusVanna"
username = "admin"
password = "ReolinkPass"
uid = "952700*****REP"

2. Launch Neolink:
3. We see the error "WARN"

Expected behavior I expected that it would connect via MQTT and entities would appear

Dropped connection is kindof my catchall for any sort of pipe that gets dropped, I will need more specifics to know which one actually caused this. I will make a build that prints something different for the different places a pipe can be dropped

Here this build, https://github.com/QuantumEntangledAndy/neolink/actions/runs/10216051705, should differentiate the different types of dropped connections so I can tell what is happening
