When you browse your web application, you may come across this error message: “Can’t reach this page. There was a temporary DNS error. Error code: INET_E_RESOURCE_NOT_FOUND”
How to solve “There was a temporary DNS error INET_E_RESOURCE_NOT_FOUND” error
As the issue mentioned, there might be a problem with the DNS record of your application’s domain. However, for an application I worked with, the root cause was the corruption in the registry settings of Internet Explorer.
We renamed the Connections container in the registry key below.
HKEY_LOCAL_MACHINE > Software > Microsoft > Windows > CurrentVersion > Internet Settings > Connections
After restarting the server, IE created a new Connections container. and the application started working.
There had been no recent code deployments before this issue started occurring. My best bet is, a Windows update or another system-level change caused this issue.
