Following of Content not working

So after setting up a SharePoint 2013 environment that consisted of two web apps, one for collaboration, the other for the my sites, it seemed the Following of Content was broken. Kept on getting an error message that stated "InternalError : Could not follow the item ..."

I used separate application pools using different accounts. When I followed content in my own personal sites the Following of Content worked, but kept on getting an error when Following Content in the collaboration site. I was unable to find any related errors in the ULS.

Could not find a conclusive answer after googling, but it seemed to be db permission related.

Solution

In SQL I added the application pool account that was being used by the collaboration site to the MySite content db and gave it SPDataAccess permission.
