Access denied when using host name for mysite

I have had a mysite working fine when set up at http://servername:81

I then wanted to set a DNS url for mysite and have it run on port 80.

-I first removed the mysite webapplication and applicationpool.

-In DNS i created:

mysiteWebapp.domain.com

mysite.domain.com

-Created the webapplication with -hostheader "mysiteWebapp.domain.com"

-Created the spsite with -HostHeaderWebApplication $webapp and -url "http://mysite.domain.com"

Added IIS entry host name: mysiteWebapp.domain.com, port 80, http, ip:"*"

I have also tried with adding extra binding: host name "mysite.domain.com" and "mysite".

I have set alternative access mapping ofr the site collection url to "mysite".

When i open the internet explorer and type in the http://mysite or http://mysite.domain.com
I get the please wait while we are working... and when the loading is ready i get a access denied after the layout:

http://mysite.domain.com/_layouts/15/AccessDenied.aspx?Source=http%3A%2F%2Fmysite%2Edomain%2Ecom%2Fdefault%2Easpx%3FAjaxDelta%3D1%26isStartPlt1%3D1362041845738

http://mysite/_layouts/15/AccessDenied.aspx?Source=http%3A%2F%2Fmysite%2Fdefault%2Easpx%3FAjaxDelta%3D1%26isStartPlt1%3D1362041799194

I have tried to remove userprofile service application, search application, mysite webapplication. And set up everything again. But i still get the same fault.

any ideas, im a bit stuck here...
