Hi, I'm having trouble running the samples/net/aws_iot sample on nRF9160-based board.
Configuration:
- nCS: v2.6.0
- modem version: nrf9160_1.3.6
When running the sample with default settings for a nRF9160-based custom board using provided overlay for nrf9160dk_nrf9160_ns board, I get the following logs:
[Sec Thread] Secure image initializing!

In the AWS I see that the device connects, shadow is updated with the message sent by the device, then the device disconnects with the following log:
{
"clientId": <hidden_id>,
"timestamp": 1732104741853,
"eventType": "disconnected",
"clientInitiatedDisconnect": false,
"sessionIdentifier": <hidden_identifier>,
"principalIdentifier": <hidden_identifier>,
"disconnectReason": "CONNECTION_LOST",
"versionNumber": 924
}
Config overlay is as follows (almost no difference between nrf9160dk_nrf9160_ns.conf file):

Do you know what may cause such error? Are you able to reproduce it? Thanks in advance.
