Minimserver takes long to show up

sometimes it takes quite long (some minutes) for minimserver to show up on my naim uniti and naim app, while the Synology media server as well as two BubbleUPnPServer instances (one proxy for the synology media server and on for the minimserver!) are available without a delay.

It happens after the NAS has waken up from standby (The DS213+ offers not only a disk standby mode but also an system deep sleep mode. You can wake it up by a normal access via e.g. http and do not need a wake on lan package.). While the original minimserver instance is not visible I can play music vie the bubbleserver-minimserver-proxy. So minimserver is up and running what is stated by the minimserver web status page, too.

What could be the problem?

My system:

Synology NAS DS213+ hardwired connected to an Asus RT ac66u router that is running as an access point. This access point is hard wired to an avm fritz box that is the internet DSL router. My naim uniti is hard wired to this fritz box, too. An android phone or apple tablet are running the naim app and connect via wifi to the asus router.

I am running the latest minimserver version.

This might be an issue with IGMP snooping on your network. When the DS213+ is sleeping, it doesn't respond to IGMP queries and would be dropped from the SSDP multicast group. The simplest solution is to disable IGMP snooping on your router (or possibly both your routers).

Some servers compensate for problems like this by flooding the network with SSDP "alive" announcements at very frequent intervals. The ohNet stack that MinimServer uses for UPnP communications doesn't do this.
