I am attempting to install OpenProject on an AWS Lightsail instance (before I move to an EC2). I have followed the OpenProject documentation for packaged installations [1] a few times but continue to get 403 and 503 errors. I do not alter content in any of the folders installed so I do not understand why this error is happening. I have suspected errors with the apache2 server so I have looked at the apache2 error.log file in var/log/apache2 and I see this message:

^ I am unsure how to proceed. Any guidance on this error using an unchanged OpenProject installation would be helpful. I am happy to provide more information from the server installation if necessary. 

In addition, when cd'ing into the openproject directory I get a permission denied error. Is it typical have to use sudo here?
