Tool manager fails to use alternate mirror when downloading packages/tools

[YukiSuter]

I'm not in Poland, but similar issue with unresolved package mirror. It appears to only want to use usc1.contabostorage.com. I think this is a core bug since it never tries a different mirror. I can confirm manually trying this URL in browser fails, but a different mirror (https://dl.registry.nm1.platformio.org/) functions perfectly fine and downloads the relevant tool. It's also worth noting even when downloaded and placed into .platformio/packages, it doesnt recognise this and attempts to download from contabo aswell. (I'm in the UK I have no idea why it thinks usc1 is the fastest)

For some more context, I'm attempting to upload code (which builds perfectly fine) to an ESP32-S3-Devkitc-1 board.
