Recently, I have been trying to connect the mqtt node on Node-Red to adafruit server. Unfortunately, it is failing to connect although it keeps on trying as shown in the screenshot below. I have configured the node correctly as shown by the following website, but no good. I have updated node red to the latest version and still.
I have a working network connection and my IoT can ping the host url:
Have anybody tried using the adafruit server before or had his/her project working.
P.S: my mqtt node can connect with the localhost server.
Your time and work are highly appreciated. Thanks in advance.
