cargo-outdated: `cargo-outdated` fails with "failed to download" error

I’ve tried both versions:

cargo install --force cargo-outdated --locked

and

cargo install --force --git https://github.com/kbknapp/cargo-outdated --locked

In both it fails with the same error type:

 $ cargo outdated
error: failed to download from `https://crates.io/api/v1/crates/core-foundation/0.6.4/download`

Caused by:
  failed to get 200 response from `https://crates.io/api/v1/crates/core-foundation/0.6.4/download`, got 502

  
 $ cargo outdated
error: failed to download from `https://crates.io/api/v1/crates/winapi-x86_64-pc-windows-gnu/0.4.0/download`

Caused by:
  [28] Timeout was reached (download of `winapi-x86_64-pc-windows-gnu v0.4.0` failed to transfer more than 10 bytes in 30s)

An attempt to run the command in a verbose mode results in bunch of warnings:

I see that these are the dependencies (direct and indirect) of my project, but I’m not sure why this happens. I have no issues running cargo update or cargo check and judging from docs in README to this repository, cargo-outdated relies on cargo update.
