The config you linked me to is in a single line, I’m not sure I understand what that is?

My config is:

proxy_cache_path /var/lib/nginx/cache-github  levels=1:2 keys_zone=github:1024m;

server {
        server_name api.github-proxy.corp.mydomain.com;

        location / {
                resolver 8.8.8.8;
                proxy_pass  https://api.github.com/;
                proxy_set_header Authorization "token MyGeneratedToken";
                proxy_cache  github;
                proxy_cache_valid  200 302 1h;
                proxy_ignore_headers  Expires Cache-Control Set-Cookie X-Accel-Redirect X-Accel-Expires;
                proxy_cache_use_stale  error timeout invalid_header updating http_500 http_502 http_503 http_504;

        }
}
