Google encountered an error when trying to access this URL. We may have encountered a DNS error or timeout, for instance. Your server may have been down or busy when we tried to access the page. Possible URL unreachable errors include:
5xx error | See RFC 2616 for a complete list of these status codes. Likely reasons for this error are an internal server error or a server busy error. If the server is busy, it may have returned an overloaded status to ask the Googlebot to crawl the site more slowly. In this case, we'll return again later to crawl additional pages. |
DNS issue | We couldn't communicate with the DNS server when we tried to access the page. This could be because your server is down, or there is an issue with the DNS routing to your domain. Make sure that your domain is resolving correctly and try again. |
robots.txt file unreachable | Before we crawled the pages of your site, we tried to check your robots.txt file to ensure we didn't crawl any pages that you had roboted out. However, your robots.txt file was unreachable. To make sure we didn't crawl any pages listed in that file, we postponed our crawl. When this happens, we return to your site later and crawl it once we can reach your robots.txt file. Note that this is different from a 404 response when looking for a robots.txt file. If we receive a 404, we assume that a robots.txt file does not exist and we continue the crawl. |
Network unreachable | We encountered a network error when we tried to access the page.
This can happen when Googlebot encounters a time-out or other network related issue when requesting a file from your site, and thus is forced to abandon the request. This can be caused by one or more of the following:
|
Failed to connect | A connection could not be established. |
No response | The server closed the connection before we could receive a response. |
Truncated response | The server closed the connection before we could receive a full response, and the body of the response appears to be truncated. |
Connection refused | The server refused the connection. |
Truncated headers | The server closed the connection before full headers were sent. |
