I've been following this to the letter with no result

I’ve been following this excellent WPMUDEV tutorial for a couple attempts so far, with no luck. I’ve got myself a droplet at Digital Ocean for just $5 while I’m trying to get my own VPS up and running for the first time. I’ve never done this before, and I really want to learn, and be successful without a shared hosting environment anymore.

This tutorial: https://premium.wpmudev.org/blog/wordpress-multisite-wordpress-nginx/

It’s great and all… but I follow it to the letter, and I don’t even deviate from the ‘standard’ names and placeholder names (like using wordpress as the username), but still it doesn’t work for me.

Are there any server studs around here that’s willing to diagnose this issue for me, or better yet… I’d even pay ya to set it up like this woman writes.

Thanks for your time.
