Hi @n0valis

Unfortunately I don't have a Raspberry Pi 4 at the moment, but I've been trying to reproduce it on other architectures and I'm not seeing that error.

I see platform: linux/arm...isn't the Pi 4 arm64?

Can you try to see if you can scrape another server? You can use https://demo.nginx.com/stub_status for testing.
