this is happening to me now same procedure from Dev to main.
Most of the pages not working except studio and home

Profile icons dont display and all the media video, logo and photo.
I'm not really new to this situation but all necessary steps i made by changing

BX_DOL_URL_ROOT and BX_DIRECTORY_PATH_ROOT 

Changes fresh Keys and secret 

manual clearing of cache 

Nothing solve the problem.
But in dev site before site.main,com/una2 it works perfectly fine
