Still having connection troubles with Nextcloud on Ubuntu 18.10

Nextcloud version (15.0.5):
Operating system and version (Ubuntu 18.10):
Apache or nginx version (Nginx 1.15.8):
PHP version (7.2):

The issue you are facing: Whenever I try to access Nextcloud I get an Internal Server Error

Is this the first time you’ve seen this error? (N):

Steps to replicate it:

  1. Point by browser to localhost/nextcloud

The output of your Nginx access.log:

192.168.1.133 - - [09/Mar/2019:22:30:33 -0500] "GET /nextcloud/index.php/csrftoken HTTP/1.1" 404 146 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:65.0) Gecko/20100101 Firefox/65.0"

I’ve been trying to access Nextcloud from my laptop (192.168.1.133) and that’s where I get the Internal Server Error. I have no idea what a “csrftoken” is, but the 404 looks like a “file not found” status. Am I reading that right?

I’d really like to get this operating, and I’m looking forward to learning more about Nextcloud!
