Accepted Answer

hello,
Here are some steps to troubleshoot and potentially resolve the problem:

**1.IAM Policies:** Ensure IAM policies allow necessary actions (iot:Connect, iot:Publish) for IoT devices.

**2.IoT Policy:** Verify IoT policies attached to devices allow required actions.

**3.Endpoint Configuration:** Double-check correct IoT endpoint and URL.

**4.Security Groups and ACLs:** Review security groups and network ACLs to allow traffic on ports 8883 (MQTT over TLS) and 443 (WebSocket over TLS).

**5.TLS Configuration:** Ensure correct TLS configuration with certificates and CA bundle.

**6.Network Connectivity:** Test network connectivity using tools like ping, telnet, or nc.

**7.AWS IoT Logs:** Check AWS IoT logs for error messages related to connections.

**8.Client-Side Debugging:** Enable debug logging on device client for detailed connection information.

i hope this will helps you ,
