google and yahoo ping failed.

Hey guys for the last couple days I received this message from the sitemap submission. I thinking it might have just been an error on that day but i've been really paying attention now and realized that it's a common occurance now. I was wondering what am I doing wrong that would cause this.

Hello,

possibly your server configuration prevents outgoing http connections and vBSEO Sitemap Generator is unable to ping google/yahoo.
I suggest you to manually submit your sitemap:
http://www.google.com/webmasters/sitemaps/siteoverview
https://siteexplorer.search.yahoo.com/mysites

is there a way to set the server configurations so it can submit it again.

There is no need to re-submit the sitemaps, google should re-download them once you have it entered in google webmaster account (you can check your sitemap downloads log via vbseo_sitemap/ interface to make sure).
