I've created a new SP2013 environment, and I can access the CA. I can create new site collections in my Web App, but I cannot access any new collections I create. Once the site is created, it simply gives me a "Sorry, this site hasn't been shared with you" message. I've tried multiple user accounts as the admin of the site collection, but none can gain access. Deleting the collection and recreating doesn't yield any results either! Authentication settings for the collection site is exactly the same as the CA, so passthrough authentication should be working as it does in the CA.
Can anyone help me with this?
