CLICK MQTT Issues

Recently cannot get any Clicks to publish to MQTT brokers. Tried multiple C2-03CPUs, V3.40. Have one on V3.3 that stopped publishing but can't verify it still has power.

 

Place all keys, topics, payloads into a Productivity on the same network and everything functions properly.

 

Have tried multiple brokers and issue persists.

 

When triggering publisher, no DNS tags change and the tag for MQTT connected does not change nor do any of the error tags change. Tried on both WLAN and Port 1, same issues.

 

Unsure what has happened with these?

    V3.41 fixed it, release notes highlight this issue.

     

    Interesting to note that connecting to V3.40 PLC with V3.41 and writing project to PLC did not trigger a FW update. PLC started publishing fine. Upon opening V3.41 fresh and reconnecting to PLC, errors showed up and FW update was required.

    After doing this to a couple PLCs I have yet to have a firmware update from 3.40 to 3.41 be forced. I have always been able to write the 3.41 project to a 3.40 PLC without issue, and then have to go back and manually update the firmware. This has not been the case with previous updates. Is this the intended operation?
