Pangolin 1.3.2 installed today using the official installer.
I am experiencing a slow download speed issue.

At first, I installed OpenSpeedTest on a remote lab machine, connected via Newt, and got speeds of around 35 Mbps down / 90 Mbps up.

For testing purposes, I ran python -m http.server on the host server, created a local site in the Pangolin dashboard, and pointed the resource to the Python HTTP server with test files. Then, I tried accessing a 1 GB test file via the Pangolin-generated link (which is served by Traefik, I believe). The speeds were around 5–10 MB/s (40–80 Mbps).

However, when downloading directly from host:python_port, I got full speed (~400 Mbps).

I also tried serving files from an Nginx Docker container via Pangolin, but the speeds remained low.

Finally, I ran a minimal Traefik configuration, as described in the Traefik basic Docker example, with Nginx as the second container. As expected, file downloads reached full speed.

I have no ideas how to debug this issue further.
There are some bug reports online about Traefik slow speeds, but no solutions are provided.
