I've recently started using Google pagespeed service which has really improved my sites performance. The only problem is I've installed sitemap generator and when I click "Crawl" after about 30secs i get the following error:
Fetching of original content failed with the following error: Proxy Publisher Failure - TIMEOUT. If you own this domain, please consult this FAQ

Have you experienced this before? And do you have any pointers?
