Describe the bug

When using Using a domain that is setup in npm (download.domain.com) stuff it is very slow (Pages loading a bit slow and maximum of 700kb/s download)

But this is only from my home.
If someone else (not from my internal network) uses it or downloads stuff, it works perfectly fine and super fast.

My Internet Speed is 1Gbit Download und 500 Mbit Upload Fiber optics
My Domain is at Cloudflare, i tested this with and without proxy enabled
I tested it directly over the domain towards my internal file server (hosted with nginx), speed is perfect
I tested this multiple days for now and the problem is definitly on npm or some mechanics when going from my network into my network again over npm.

Nginx Proxy Manager Version
2.12.1

To Reproduce
Steps to reproduce the behavior:
Setup a Subdomain towards npm
Setup the proxy host in npm towards a webserver hosting files
Try downloading the files.

Expected behavior
Slow Speeds

Operating System
Docker Container on a VM with 8gb ram and 4 cpu cores
The vm is on a Server with 128gb ddr4 ram and intel xeon v4 28 cores (56 threads) and ssd´s
and the server is not even using more than 50% of cpu or ram

I'm also experiencing this. It seems to be really down to NPM.

When i access the service directly, i get full download speeds. when NPM is in the middle. it slows down to 55-120 mbit.

Then when i go to WAN... the speed is unlimited..

I'm also having this issue, but weirdly it's not an issue on my Android phone (tested in Chrome, Firefox and the relevant mobile applications). My Android tablet, though, gets: ERR_SSL_UNRECOGNIZED_NAME_ALERT and won't load the pages at all.

I'm on version 2.12.3

UPDATE:
Ticking on HTTP/2 Support fixed this issue for me, everything's working like a dream now.
