I set up a small Digital Ocean droplet a while ago to host my side-project, and while doing it made sure all http:// requests redirect to https:// (using Lets Encrypt certificates). I'm using nginx as the web server. However, I now need to make some changes and cannot remember how I configured nginx to redirect to https every time. I've uninstalled nginx (sudo apt-get purge nginx), which removed all the files.
I have now re-installed nginx, but nothing loads; even just going to http://DROPLET_IP redirects to https://DROPLET_IP but then fails to load (not even hanging, just a quick no-response from my browser). However, I've tried to set up a couple of my nginx virtual hosts but these redirect as well, and do the same as above.
All the config is set to the default, including nginx.conf and sites-available/default (symlinked to sites-enabled/default).
tl;dr: nginx was previously configured to somehow redirect every request to https://, but I now need to disable this but can't figure out how I originally did it.
Is it possible there is another nginx installation somewhere, screwing things up? Or some files hanging around from the previous installation? All the files are located in /etc/nginx, and when I purged nginx from the system I made sure to check they had been removed before re-installing.
My Droplet is running Ubuntu 16.04.
Running netstat -lpnI get this output:
