You can try this basic policy;

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

Currrently only iot:Connect and iot:Publish are used. Connection is lost even if nothing else is done after connecting to broker.

What AWS policy are you using?

They are already enabled and disconnect is casused by "disconnectReason": "CLIENT_ERROR". According to AWS IoT documentation this error is caused by client doing something wrong. However I haven't been able to figure out why is that. Completly identical code works without errors in nRF9151DK but still problem persist only with Thingy.

Can you enable AWS IoT lifecycle events to check if the disconnect is caused by a policy issue?

Thanks, I don't see any clear cause. But I have forwarded the trace to the modem team so they can also have a look.

Sorry for the delay, I have been busy with other projects. Modem trace is now added to attachments.

Hello,

can you please provide a modem trace, and make sure that the failed connection attempt is part of it?
