This item could not be crawled because the repository did not respond within the specified timeout period - SharePoint Search Error
Environment: WSS 3.0, Microsoft Search Server Express 2008
The Search server is crawling the contents properly and the search is working as expected. Suddenly, search crawling stopped and the error in the Search log is
"This item could not be crawled because the repository did not respond within the specified timeout period. Try to crawl the repository at a later time, or increase the timeout value on the Proxy and Timeout page in search administration. You might also want to crawl this repository during off-peak usage times".
I understood that the error is due to the Proxy and checked the Proxy and Time Out settings in Search Server Administration and it is 120 Seconds.
Then, removed the Proxy Settings configured in the IE. Followed by an incremental crawl fixed this issue and I didn’t see any errors after that.
Also, uncheck the option in the IE “Automatically Detect Settings” (if it is checked).
Here is the link which gave the complete solution for this issue:
