Doubt as which user apache2 and other services run as

Hello, I deployed nextcloud via hestiacp, and I managed to make it work fine, besides using redis socket.

I followed many tutorials and checked many forums, and it’s not working as it should. I triple checked configs etc.
So it came to my mind, that might be user permissions fault (since doing the checks as www-data seem to work fine)
Does apache2 run as “myhestiauser”? What other services run as “myhestiauser”?
