Hi
When I request a package from our Nexus Proxy for something that I can find on [npmjs.com](http://npmjs.com) it is often the case that the latest version on [npmjs.com](http://npmjs.com) is 1-3 days old but that latest version is not present in my Nexus Proxy.
How does Nexus deal with updating versions of packages?
- Does it work on a timing basis?
- Am I able to force it update for a particular package and version?
- Does it recognise that I am asking for a package version that’s newer than the version already stored so it should then go and download it?
Currently I just get ECONNCT issues or 404 when asking Nexus for the latest verson.
Any help greatly received as this type of thing really slows down my development cadance.
Thanks, Mark
