Schedule task work properly manually. But not automatically.

All the schedule task properly by clicking run now button but not at startup nor even after a specific time. Getting the bellow error continuously. There is no loadbalancer or webfarm. Singel server PC. I saw some similar topics but do not get a solution.

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

My bad. It was the host file change issue. The domain was not mapped for the IP. Just sharing details so that others can get help.

To resolve the issue I have to go at C:\Windows\System32\drivers\etc
then edit host file like bellow
10.10.2.300 yourdomain.com
10.10.2.300 www.yourdomain.com
like your bind IP of the website and domain name.
yourbindip yourdomain.com
yourbindip www.yourdomain.com
