Videos not showing up after upload CB V4.1

Hi,
I have a fresh install of CB on CentOS 7 using Nginx. After uploading a video it never show up on the site. If i look at the back end. I can see the conversion completed successfully. Files are moved into /file/videos/ etc like they are supposed to. They never show up in the video manager. I looked in the DB and they are not listed in the video table. I tried to add a user through the user sign-up and it would just bring me to a blank page after i filled in all the info and never added to the user to the DB. If i try ti manulay add a uset through the admin console i get This page isn’t working

sitename is currently unable to handle this request.
HTTP ERROR 500

It is as if the site is unable to write to the DB, but it is not showing any errors. I am seeing these errors in my Nginx log file:
