Good day.  
I am trying to send a message to iothub but I get this error. This was working fine until a few weeks ago. Do you know why it usually fails?

How do i fix it?

Hello and welcome to the forum.

The key error I see is the "could not connect", and the red "disconnected" note on the node.

So, some setting in your node (which we can't see), or in your hardware (which we also can't see) has changed. Node settings? Hub Power (turn it off and on again)? Hub connection to your router? Monkeys?
