Your topic syntax is incorrect. The syntax has changed from the previous MQTT broker. Have a look at the MQTT publish to a feed documentation for the correct syntax. Make sure you enable the device to publish to the channel you intend in the MQTT devices section.

then this should be correct?
mqtt:
broker: 'mqtt3.thingspeak.com'
port: '1883'
username: 'username'
password: 'pass'
client_id: 'clientid'
discovery: 'false'
discovery_retain: 'false'
topic_prefix: 'channels'
interval:
- interval: 3sec
then:
- mqtt.publish:
topic: channels/1462749/publish
payload: field1=5&status=MQTTPUBLISH
qos: 0
retain: false

looks better! Did you add the channel to your MQTT device permissions? If so, I think it should work.
Do you have a paid license? If not, the interval (3 seconds) is too small, you can only publish every 15 seconds for a free license, and you would be wasting seerver time with the extra requests.
