After updating to 1.28 I got an operation timed out when installing a toolchain

I have a somewhat slow connection, but I've never had a problem before. I tried several times and got the timeout consistently. I finally managed to install the toolchain by setting RUSTUP_USE_CURL.

It may be related to #3486, but I'm posting it as a new issue because I never had a problem before updating.

Steps

I'm not sure if you only need a slow connection or if there's something particular about my network, but I get the error when I do rustup toolchain install. My toolchain file has

[toolchain]
channel = "1.85"
profile = "minimal"
components = [ "rustfmt", "clippy" ]
targets = [ "x86_64-apple-darwin", "aarch64-apple-darwin", "x86_64-unknown-linux-gnu", "wasm32-wasip1", "x86_64-pc-windows-msvc" ]

I think I'm having the same problem, my company limits internet speeds

Looking at the changelog I see that it is indeed the 1.28 update that is causing the problem
#3798

Thanks for the report. This looks like quite an old bug in the reqwest backend that wasn't noticed because it wasn't the default until recently. I filed #4218 to fix it.
