WordPress can not find my server

I have followed the instructions at

http://codex.wordpress.org/Create_A_Network

and

http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory

but get the message

“Forbidden

You don’t have permission to access / on this server”

when accessing my sub domains (or example http://blog.bsharp.se/)

but when I try bsharp.se it is working

And also when I want to activate my jetpack plugin it can not find my server. The message I get is:

“Your website needs to be publicly accessible to use Jetpack: site_inaccessible
Feldetaljer: The Jetpack server was unable to communicate with your site [HTTP 403]. Ask your web host if they allow connections from WordPress.com. If you need further assistance, contact Jetpack Support: http://jetpack.me/support/”

I started with my site http://www.bsharp.se/blog/ and used the page (one of the above in the start of this message)
http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory

and the section “Using a pre-existing subdirectory install”

I also want to move the blog site that now is the main site to the blog.bsharp.se .The old blogs at bsharp.se/blog/ is still accecible from that folder and is still correctly linked.

When installing Multisite my intention was to use sub-folders, but during the installation I got the message that since I already had sub-folders the domain alternatives was the only possible.
