I’ve been using HiveMQ basic cloud account to learn and implement some IoT devices. Last friday at 9:15 all my devices stopped working and now only LWT messages are received by the mqtt server, everything else is not working anymore.
When I made a paid account everything started to work again.
I am using Tasmota firmware in 7 devices, and have one android app, one raspberry pi and one computer connected to the save server.
I could not find any answer to understand if I violated a quota of messages or something like that. Any ideas about what happened to me?
