Im having some trouble with google sitemaps.
Everytime I submit my sitemap to google it takes a good hour to tell me that it couldnt download it.
I have a redirect on my main domain, pointing all users to a subfolder within the site, so Im guessing its also redirecting the googlebot crawler.
Does anyone know how to exclude the crawlers from being redirected? (if this is whats happening)

Any help is much appreciated.
