Hello, I am trying to connect an IOT device to a HiveMQ Cloud cluster. I have made credentials using the cloud cluster and use the server certificate provided. I am able to connect using mosquitto-client software but when I try the connection using my IOT device the server rejects the connection. The device I am using is a Quectel LTE module. I have spoken with Quectel and they traced the issue back to the server connection.
Any ideas why the connection is rejected when using my IOT device? See below image;
