RE: Problem installing CHIP tool

I am running macOS.

I can reach directly:

HTTP/2 405

content-type: text/plain; charset=utf-8

allow: GET, OPTIONS

x-content-type-options: nosniff

x-cloud-trace-context: e39af654636f95d54248ce4268b9533b

server: Google Frontend

cipd logout does not work.

Tried many tricks including erasing cache - nothing works.

I could change SDK - works smooth with e.g. SDK 3.0.0 , but it is cumbersome - would love to stay on current SDK.

Hi,

Are you on Linux or macOS?

I was not able to reproduce the issue on my side (Ubuntu 24.04), so it does not seem to be an issue with the OAuth client ID in v2.7.0.

It could be the network. Are you behind a corporate proxy, firewall, or VPN? If so, can you try without VPN or with a different network?
Since the issue is reaching https://ci.chromium.org, can you see if you can reach it directly from your network? For example, with

curl -I https://ci.chromium.org

It might also help clearing CIPD credentials and cache:

cipd logout
rm -rf ~/.cipd-cache
rm -rf ~/.cipd-cache-dir

Have you tried newer versions of the SDK?

Best regards,
Marte
