Removed: `include conf.d/proxy-confs/proxy.conf;` lines because they're specific to user (shauder) and will break nginx if copy-pasted/don't exist.
Changed: Moved listen value and server_name to top as is standard for nginx configs
Changed: Commented out SSL config as it's specific to user (shauder) and will break if copy-pasted/don't exist. But is still useful and a good idea for simplifying nginx config.
Changed: Rearranged location blocks because OCD. First /, then /notifications/hub, then /notifications/hub/negotiate because it looks nicer in a tree where each location grows.
