@Boopathi S Thanks for reaching out. The time out error on Device Setup mostly shows that something is wrong. In most of the scenario which I have seen, the deployment of the application or installation would have failed which is causing the setup to show this default message.
To narrow it down, you can collect the MDM logs, when you see this error message, press shift+F10 this will open up the Command prompt.
You can then type in mdmdiagnosticstool.exe -area Autopilot -cab c:\autopilot.cab to collect the autopilot logs.
1) They will help you troubleshoot what went wrong. As these might contain huge set of logs, you can contact Microsoft support with these logs to get a quicker resolution.
2) Or you can reverse engineer on a normal windows 10 machine by deploying applications and to find which one fails using event viewer or Intune portal.
If the application fails in normal enrollment, that will also fail during Autopilot causing you to exceed the time provided and give up that error message. Hope this helps.
