Getting a blank page while for matomo/index.php

This is the 1st time I am setting up the environment for Matomo, I have installed Apache and php with all required extensions like pdo_sqlite, pdo_mysql, mysqli etc on 1 VM and DB on another. Post this when I am hitting matomo context it is giving blank page to me.
Note: Apache is working fine.

How can you be sure?

Do you see anything in some error log file (Apache, PHP or Matomo)?
Were you able previously to configure anything for Matomo (first configuration page, etc.)?
