Timeouts on a Rust release build on windows

I have a project in rust that I want to build on linux, mac and windows. when trying to build a release build, the windows build timeouts with “No output has been received in the last 10m0s,…” and the last message is a cut " Dow" line that should be from cargo downloading dependencies.

Here’s the build in case, it’s a release build of a tag:

interestingly the same commit from master (so no release build) worked on all 3 platforms.

here’s the .travis.yml file https://github.com/gdamjan/http-server-rs/blob/master/.travis.yml

might this be related to the GITHUB credentials issue?

been awhile, but as of today windows and rust seems to work fine
