Type: This is a 'Warning' message (Orange highlight).
Source: This originates from the Vector itself.
Symptoms: The device may or may not be operating correctly dependent on the cause of this error.
This error means that sending of data via MQTT is not possible, but other more relevant errors may also be present.
Cause: If the device is working correctly otherwise, then the most likely cause of this error is a mistake in the HTTP Post settings, such as a spelling mistake in the destination URL, or a network issue such as a DNS IP lookup issue.
If the device has other error messages present then these will most likely lead to the cause of the underlying issue.
Fix: To fix this issue, either check the MQTT settings, or correct any other errors present.
