Connection to MinimServer takes >5 min

This sounds like a problem with UPnP multicast discovery on your network. The long connection time for the AudioStation server appears to confirm this. If multicast discovery is working correctly, both devices should be discovered in a few seconds.

You can find more information about multicast discovery problems on this page. As a first step, try powering off all your network equipment (router, switch, access point, etc.) as well as your NAS and your audio equipment and then power everything on again. If this doesn't help, check your router configuration to make sure IGMP snooping is not enabled.
