If you are using the MQTT protocol in any of your IoT projects to communicate with IoT Cloud, then you might aware of the following errors.
Attempting MQTT connection... Failed. rc=-1 or rc=-2 or rc=-3 or rc=-4 or rc=-6.
These are the general errors you will get while trying to communicate with any MQTT servers.
my channel/website comment box and email flooding with these types of errors to seek help to solve these errors every day. I have been answering these emails for a long. but the number of people is increasing and it is very difficult for me to reply to everybody. therefore, I have decided to make a video to explain these MQTT error codes and show you how to solve these.
