Hosting Ghost on Digital Ocean with Cloudflare

I'm currently using GhostPro for hosting my site, but recently tried setting up a test instance in Digital Ocean with the domain managed via Cloudflare.

Everything was installed according to the docs, but I ended up receiving an error when trying to go to the custom domain with a "Too many Redirects" message.

After spending about half an hour searching for a solution and messing with the Nginx configuration, I came across this comment on Github

I couldn't find a "Disable Universal SSL" option, but setting the SSL/TLS encryption mode to "Full (strict)" from within the SSL/TLS -> Overview settings did resolve the issue
