I have an AWS IoT button (2nd Gen) that I am able to successfully connect to a portable hotspot and send notifications through, but when I try to reconfigure the button to run on a Wi-Fi network, I keep getting a short long short red light pattern.
Here is the AWS explanation for the error:
There was an error performing the host name lookup. This can be the result of not being able to reach the DNS server or an incorrectly configured AWS IoT endpoint subdomain.
I read that there might be a DNS caching problem, but I am unaware of any way to reset the button and I've tried waiting to see if the cache would correct itself.
Does anyone have any suggestions for what to do next?
