Internet Explorer error "connection timed out" when server does not respond

When you connect to a Web site that runs for a while before it returns information to Internet Explorer, you may receive one of the following error messages.

Error message 1Error message 2Error message 3

Internet Explorer imposes a time-out limit for the server to return data. By default, the time-out limit is as follows:
When the server is experiencing a problem, Internet Explorer does not wait endlessly for the server to return data.



Applications that use the WinINet API directly will experience the following ReceiveTimeout values:


You can locate the version of WinINet.dll in the %windir%\system32 directory.

If a page does not return within a few minutes, many users perceive that a problem has occurred, and they stop the process. Therefore, you should design your server processes to return data within approximately five minutes so that users do not have to wait for a long time.

You can usually break down long processes into smaller pieces. Or, the server can return status data to update users about the process. In addition, you can create a long server process that has a messages-based or asynchronous approach so that it returns immediately to the user after the job is submitted, and then notifies the user after the long process is finished.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: Although Microsoft does not encourage this approach, you can change the default time-out setting for Internet Explorer.

To have us change the default time-out setting to 5 minutes for the Internet Explorer, go to the "Fix it for me" section. If you prefer to fix this problem yourself, go to the "Let me fix it myself" section.

Let me fix it myself

To change the default time-out setting for Internet Explorer in Internet Explorer 4.0 Service Pack 1 (SP1) or a later version, follow these steps:

1. Start Registry Editor.
2. Locate the following subkey:
   HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings
3. In this subkey, add a ReceiveTimeout DWORD entry that has a value of (<number of seconds>)*1000. For example, if you want the time-out duration to be 8 minutes, set the value of the ReceiveTimeout entry to 480000 (<480>*1000).
4. Restart the computer.

Note This setting becomes the new global timeout which applies to both Internet Explorer and any WinINet application.
