Nexus won't download artifacts from Central

Argh! DNS issue - using the IP address in the maven settings.xml fixed the problem.

I've just installed Nexus 2.2-01 behind a corporate proxy. Maven is working when I go direct to the Central repo, but when I configure the
<mirror>
in%M2_HOME%\conf\settings.xml
I can't do a simplemvn archetype:create
ormvn clean
.From the Nexus web UI I can:
- "Browse Remote" in Central.
- "Browse Index"
- and from the "Artifact Information" tab where it says "(Not Locally Cached)" I can download the jars
- and then see the .jar and .jar.sha1 files at "http://127.0.0.1:8081/nexus/content/groups/public/" and "\nexus\sonatype-work\nexus\storage\central"
...but for some reason it does not download the
.pom
filesNexus 2.2 came with a proxy repository for Central pre-configured, and I can browse the index and download files manually from the web UI - so why won't it work from Maven?
I have configured Nexus with Default HTTP Proxy Settings with Authentication, but still get errors such as:
