Describe the bug
Very slow loading times when behind Cloudflare proxy. Not going through Cloudflare proxy works fine. Issue showed up in 2.11.0, as rolling back to 2.10.4 resolves the problem.

Nginx Proxy Manager Version
2.11.0, 2.11.1, 2.11.2

Additional context
May be related to #3365?

As stated on #3365 running this project behind a proxy isn't really its intended purpose. That said, just like any other website, there shouldn't be a problem. Are you proxying to NPM over HTTP or HTTPS?
