Error Message

The EV client trace shows the search timing out after the configured 110 seconds in the example below:

02:56:02.473[4732][H]: HDR: Requesting page: SyncPoint.aspx?Slot=0d59f676-81fa-48b5-b05b-5000fdc84e16&ArchiveID=16F9A835C63464F449F161C6D2A6313501110000EVSite&SyncPoint=0&SiteID=1F4C598219829014BBA2908DB61BCB6E41d10000EVSite

The client trace alternatively could also show the following:

A Dtrace of the W3WP and EVIndexQueryServer processes will show the following with the same 110 seconds delay:

Alternatively, the dtrace could also show the following:

WinHttpRequest::OnCallback. WINHTTP_CALLBACK_STATUS_HEADERS_AVAILABLE. Status code=502
WinHttpRequest::OnCallback. WINHTTP_CALLBACK_STATUS_HEADERS_AVAILABLE. Error status but no X-EV-HRESULT, so returning E_FAIL.

CIndexQueryServerSearch::Search2. Request FAILED HR=0x80004005.

This issue can be caused by a WINHTTP proxy being configured on the EV server.

1. Remove the proxy server via the command:

2. Add the EV server to the bypass list as documented in the following article:
