Failed sending data to the peer with latest nightly

[fourbytes]

Problem

Builds inside docker containers (CI) seem to fail on nightly versions > 2021-07-05.

error: failed to compile `sccache v0.2.15`, intermediate artifacts can be found at `/tmp/cargo-installYaFAmQ`

Caused by:
failed to download from `https://crates.io/api/v1/crates/async-io/1.6.0/download`

Caused by:
[55] Failed sending data to the peer (Connection died, tried 5 times before giving up)

Steps

1. Build a project inside a docker container.

Possible Solution(s)

Using nightly 2021-07-05 with rustup default nightly-2021-07-05 appears to fix the issue.

Notes
May be related to #6513.

Output of cargo version:
cargo 1.55.0-nightly (3ebb5f15a 2021-07-02) (oddly this is the same version that seems to fail in the latest nightly builds).

Is it a duplicate of rust-lang/crates.io#3782?

Yep, apologies, searched for the error but didn't see any results.

The next nightly (in about 12 hours from the time of this post) should have a temporary workaround in #9695.

Looks like this has been fixed in curl curl/curl#7400. Going to close as resolved.
