Fixing Foundry Install Errors — The Fastest Shortcut

If you're setting up Foundry and trying to install via:

curl -L https://foundry.paradigm.xyz | bash

…you might hit the annoying error:

error: download of config.json failed
Caused by: [28] Timeout was reached (Connection timed out)

Or even worse — foundryup never installs and every command returns:

foundryup: command not found

You’ll start Googling, clearing Cargo cache, tweaking DNS, and doing everything except actually writing Solidity.

After an hour of fighting it, here’s the real fix:

🧠 The Solution (No BS)

Use a VPN.
That’s it.

WSL sometimes has terrible routing to GitHub CDN endpoints depending on your ISP. Cargo fails, curl fails, wget fails — and it’s not your fault.

I turned on Surfshark → re-ran the install → it worked instantly.

🎤 TL;DR

If you ran into this issue, just use a VPN bro. END
