I’m currently trying to migrate from nexus2 to nexus3. Most of my repos have worked, but with one I’m currently struggeling.

Its a simple hosted repo with some npm packets in it.

The scan works just fine, but after that it always breaks with http disconnection read timed out.

Here you can see the logfile during the upgrade:

How can I get that repo upgade to work? Both machines run on the same server.

Thanks!
