Issue/Introduction
A (short) network interruption may get undetected but when a job is started during the interruption, you may get this message in AWI (read bottom up):
The interruption is detected on the AE and Agent side with the following messages:
CP log:
20260226/125046.098 - 57 U00029416 Agent Challenge authorization successful : 'WIN-AE24-JAVA'

Such a network interruption can be simulated by temporarily switching off the network card on the remote Agent side using this Powershell command:
Disable-NetAdapter -Name "Ethernet" -Confirm:$false; Start-Sleep -Seconds 60; Enable-NetAdapter -Name "Ethernet"
Or this Linux command:
sudo ip link set eth0 down && sleep 60 && sudo ip link set eth0 up
Cause
The root cause is network interruptions
Resolution
Check with your network team to investigate and improve the network.
