500 error on new installation

Hello,
I tried the demo, and now I want to install on my own instance. I am installing Leantime on a RunCloud managed server using NGINX+Apache with PHP 7.2 and Maria DB.

I am getting a 500 error when I run the installation at https://sub.domain.tld/install

The Apache access log shows me hitting the server but the error logs show nothing.

Do I still need to configure nginx even though it is running Apache?
Can it run on MariaDB?

What else might I be missing?

Thanks,
Matt
