I think all those builds are based on an outdated version of the master branch as the failing tests do not exist anymore in the code, rebasing onto master should solve the issue, but @JoshuaLai can look deeper if needed.

Please note that we are experiencing some issues in the service that are being tracked with an IcM and that is causing the 403, but the new set of tests do not hit the failure path.

The C# live tests have been running and passing successfully for the past week, I think we are okay to close this.
