Good Morning All,

I’m currently experiencing difficulties connecting my MQTT transmitter to the MQTT distributor.

**Setup Details:**

- MQTT Distributor Version: 4.0.21
- MQTT Transmitter Version: 4.0.21
- Connection URL: `tcp://localhost:1883`

**Debugging Steps Completed:**

1. Added inbound and outbound rules for port 1883.
2. Verified connection to the distributor using MQTT.fx with the correct user credentials. Which I can publish and subscribe.
3. Reviewed the [Cirrus Link Documentation](https://docs.chariot.io/display/CLD80/I+created+a+Transmitter+but+my+MQTT+Transmission+module+does+not+show+connections+to+my+MQTT+Server) for applicable solutions.
4. Checked logs, which continuously display "Starting up Agent."

I any suggestions on how to resolve this would be a great help!

Thanks,  
Ryan
