MQTT Disconnect, won't reconnect without reboot

We have a device that has been connected and working fine. Then it will disconnect and not ever reconnect again. However, if the device is unplugged and plugged back in, the device connects fine.

How would you recommend troubleshooting this issue?

Hi @Steve_Ermish!

What error message(s) are you seeing in the device connection log?

Based on your description, it sounds like an issue with device-side code. The device might be only attempting to establish a connection on boot and never disconnections or uncaught exceptions.

A few additional questions:

  • Are you using one of our client libraries?
  • Do you mind sharing any client-side code from the device?
  • Do you have any logs from the device?

Also, do you mind providing the device ID so that we can take a look?
