To solve the problem, you need to restart the MQTT connection. You also should check your application settings on your server.
Check the IIS Configuration of your server
- MQTTBrokerIsLocal => Must be set to true
- MQTTBrokerAuthority => Needs to match your server address with the port 1883
Restart the MQTT Broker on your server
- Click on the button Restart Mqtt connection (wait for a minute and refresh the page) If the state still shows disconnected, try Step 2
- Restart your server. If after your server restart, the MQTT still doesn’t connect correctly, then please contact the support team.
