HTTP Error + cURL Error 28 – Fresh Install

Firstly, I havent done anything with the site yet, so it’s blank…

I am hosting this myself and running Nginx as both front end and reverse proxy for Nginx Unit to handle the backend.

Up until I installed SSL from letsencrypt, I was able to upload files with no problem.

I have uninstalled and re-installed wordpress, I have uninstalled and reinstalled both nginx and nginx unit – Nothing seems to get it to work once my site has an SSL Certificate.

Here are my server logs: https://hastebin.com/aravenejih.m

I repeatedly get the HTTP Error on the media upload screen, and no error shown on the frontend when trying to change theme, although I get the cURL error 28 and a broken pipe error shown in the logs.

If you need to see the config files – I can get them – I have tried nearly every possible “Fix” I can come across through various forums, and it still repeats – Any help would be appreciated.
