Hi! I have tried to connect from the testing environment ( https://testing.opensensemap.org/ ) to HiveMQ over MQTTS and after a minute or two published messages aren't saved anymore or the client disconnects. I ran the project locally and the connection isn't closed, all the messages sent to the broker are received, even after 15+ minutes running. The same behavior happens when trying to connect over MQTT to https://dioty.co/ from the prod environment ( https://opensensemap.org/ ). Changing the topic or connection options and saving the config makes the connection work for the next 1-2 minutes. The integration with MyQttHub works perfectly in the prod env, the client doesn't disconnect. Is this a testing environment specific issue?
