Maven Metadata Endpoint(s) returns 404

While attempting to set up registry.quarkus.io as a Nexus Repository Proxy following the instructions in README.md, the publishing check fails with an "Item Not Found" Exception. The issue originates from the URL https://registry.quarkus.io/maven/.meta/repository-metadata.xml, leading to an unpublished proxy. A 404 error is encountered when using the curl command on the mentioned URL:

My preliminary assumption is that there might be an infrastructure or deployment issue, given that the tests against this endpoint in the application code are executing successfully.

I would appreciate it if you could verify whether the endpoint is configured correctly.
