I just upgraded my Sonatype Nexus instance from version 2.14-01 to 3.1.0-04.

I followed the upgrade steps and everything appeared to work correctly.

The problem I am having is I can no longer view the repositories if I am not logged into Nexus.

Under Nexus 2.x, I was able to view the repositories and run searches without being logged into Nexus. Now I need to be logged into Nexus for this to work.

Is there a setting in Nexus I need to update to allow users who are not logged into Nexus read only access?

Thanks
