I am having trouble getting the MQTT ouput block to connect to Amazon Web Services. It will go back and forth between "connecting" and "disconnected". Does anyone have any experience using AWS? I have tried looking for some sort of guide on Amazon's website but have not found anything to be useful. Thank you in advance.

What client is this ? Python? Embedded, etc.?

I am not really sure about the client. This is the error I am getting in the Debug tab:

I have triple checked the route to the file and don't understand how this could be the issue.

For windows you may need to escape the \ with another . So G:\. Etc. Or use / instead ?

Neither seemed to work. I don't understand why there is an issue with the route of the certificate, but the private key and CA certificate are fine. All are in the same folder.
