I'm on the Azure SDK team and we have a few snapshot builds of packages hosted on oss.sonatype.org. On some machines the following request fails with a 403 Forbidden.
The package is: email@example.com-SNAPSHOT
Interestingly when I download from my local machine, the Server: header I get back is nginix, but when I download from Azure Pipelines hosted agents I get a Server: head back of awselb/2.0 (which makes sense since it appears to be hosted on AWS).
Just wondering if there is a corrupt cache somewhere which is impacting some of your routes.
