CI can't reach internet to fetch rust packages

[David Mulder]

I'm getting this failure when doing a `cargo test` via samba test in CI:

     Updating crates.io index
warning: spurious network error (3 tries remaining): [7] Couldn't 
connect to server (Failed to connect to index.crates.io port 443 after 
42 ms: Couldn't connect to server)

error: failed to get `libc` as a dependency of package `config v4.21.0 
(/builds/samba-testbase/samba-o3/rust/config)`

Caused by:
   download of config.json failed

Caused by:
   failed to download from `https://index.crates.io/config.json`

Caused by:
   [7] Couldn't connect to server (Failed to connect to index.crates.io 
port 443 after 0 ms: Couldn't connect to server)

Doing `cargo build` during the build phase does not fail to download 
dependencies. Any one know what's causing this?
