Missing ACKs

Overview

• A Confirmed-Request needs an acknowledgement, or an Abort, Reject, or Error. If you don’t get any of those, it’s a Missing ACK.

Why it fails

• The destination device is offline.
• The router that it goes through is offline or busy

How to fix it

• Check if the destination device is unresponsive.
• If it’s unresponsive, then that’s why you have a missing ACK. Otherwise, check what’s in between.
• Check unresponsive devices, to see if they’re going online and offline.
