Timed Out Description & How to Fix
Response from the server was not received on time when requesting a page or resource.
This may damage your website crawlability (and thus indexability) and have a negative impact on the user experience.
How to fix
Try to reproduce the server error reported by Site Audit for these URLs in your browser. You should also check the error logs for your server. If this is an ongoing problem, you need to check with your hosting provider or with your web developers. Your server may be overloaded, misconfigured, or very slow.
You should also note that this can be a temporary issue, e.g. when the crawl took place during some maintenance on your website's server.
