Connection times out when trying to connect to IoT Core on Portenta H7

Question

I am trying to connect to the MQTT broker and it says connection timed-out. The policy allows all actions and even the internet connection speed is fast.

Answer

Hi Atharva. Please refer to our [Diagnosing connectivity issues](https://docs.aws.amazon.com/iot/latest/developerguide/diagnosing-connectivity-issues.html) documentation if you haven't already.

If that doesn't help you resolve the issue, please then provide device logs and other relevant information about your connection such as protocol (MQTT or MQTT over WebSocket), port (8883 or 443), authentication type (X.509 certificate or something else), your IoT policy etc.

I am connecting to the **MQTT** broker on port **8883** with an **X.509** certificate. This is my IoT policy:

```
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "*",
      "Resource": "*"
    }
  ]
}
```

I am following this guide:

but I am trying to connect an Arduino Portenta H7.
