I am using an external hardware (Advantech ADAM 6717) from which I need emails to be sent based on the readings. But, when I try to test the email functionality via the Node red on the hardware, I am getting the following error.
How to rectify it?
Am I doing a mistake here? I have connected the hardware to the static IP address for remote access. I am able to obtain the remote access, but only the email functionality is not working.
