Reconnect your MQTT Devices


#1

We recently had a short dashboard downtime which was determined to be related to our monitoring of the online / offline status of MQTT-connected devices. We’ve pushed a fix for that today so a similar downtime can’t occur for the same reason moving forward.

One of the side effects of this fix is that it will be necessary to re-connect any MQTT devices to Cayenne in order to display accurate online/offline status and to ensure best performance of other Cayenne features. To do this, if you have a microcontroller like an Arduino/ESP or similar device, please power cycle the device to ensure a reconnection. If you have a Linux based device running a Cayenne MQTT client, a reboot isn’t necessary, you can simply stop and re-start the client to reconnect.

If you have any questions about this or suspect ongoing MQTT device trouble, please feel free to ask here or make a new thread. Apologies for this inconvenience - it should lead to greater platform stability in the future!

I keep getting a red maintenance banners on my iOS , multiple banners. Are you still fixing?


#4

@wmontg5988 we are not, and weren’t at the time you wrote this either. I suspect it something on our server side that caused the iOS app to get a 5xx status code and decide we were under maintenance when we really were not.

Please try again and let me know if the issue persists.


#5

It’s giving the same error again today.


#6

Can you try force closing the app (by swiping it off screen from after double-tapping the home button) and re-launching, to make sure its not stuck in that state?


#7

I had actually removed and reinstalled the app this weekend but now it has stopped on its own without any intervention.


#8

Yeah I’m seeing 503 errors in my web browser so I think our server is acting up – hang tight, we have our IT looking at it.


#9

Yeah started again and my devices are gone. Standing by😁

@wmontg5988

I’m still waiting for any word on what happened from our engineers but I know the 503s on my end have cleared up. Are you still seeing the Maintenance message in the iOS app?
