Is the new minimserver 0.83 incorporated changes to work better with naim app?Reason I'm asking is I have on many occasions naim app cannot find minimserver when i click on the upnp icon on the app.

e.g 1, listening to spotify, click on upnp cannot find server. Restarted laptop and all is well.

e.g 2. While listening to some track on upnp and when i click back to all albums, naim app hangs there and lost connection to minimserver. Click on app upnp icon again and the app is trying to search for minimserver without success. Everytime I restarted laptop all is well.

I am not sure if this is a naim app or minimserver issue but it seems you know of some pending problems between naim app and minimserver.

Thanks for any adivise.

These problems are usually caused by network multicast issues. There aren't any changes in 0.8.3 that would make a difference to this. The other possibility is an issue with the Naim app. I have had similar problems with the Naim app sometimes not being able to find the Naim streamer.

There is a fix in 0.8.3 for a problem that could cause incorrect cached browsing results to be shown by the Naim app. This isn't related to the problems you are having.

What platform are you using to run MinimServer? If it is a NAS, do you have a VPN server running on the NAS? This can cause network discovery problems.

Hi,

Minimserver is running on a laptop, no VPN server. Do you have any recommendation as a control software other than Naim App? I'm using Naim Unitiqute as a streamer. Thanks.

If you have an Android device, you could try BubbleUPnP. I don't know of any good control points for iOS.

The most likely cause of the problem is your network multicast configuration. If you search this forum for "multicast", you should find a lot of previous discussion on this issue. What router are you using and does it have a setting named something like "multicast" or "IGMP snooping"?

I'm using a Apple Airport Extreme and it does have a multicast setting which is set to low now. Should I change it to medium or high?
Thanks.

I'm not familiar with this device or the way it handles multicast traffic. On most routers, the setting is just off or on. You could try changing it to high to see whether this makes a difference.

I am having the same issues with discovering the minimserver on a Synology NAS in combination with the NAIM app. I use Apple Time Capsule, toggled IGMP Snooping, multicast rates etc. but no improvement. It appears and the moment after it is gone. The Synology mediaserver is 'behaving' better. Is there a way to change the SSDP? Any options I can try? thx!

Do you have a router as well as the Time Capsule? If so, which router is it? Does the router have any settings for IGMP snooping or multicast?

Yes, the router is the Time Capsule. I toggled the IGMP snooping on/off. Multicast set to low/middle/high. No result. Another Time Capsule is hardwired to the 'Router' Time Capsule throught ethernet cable. The Time Capsule which is in bridge mode is connected tot the Synology NAS. Direct connection to the Router doesn't help also.

Please try setting IGMP snooping to off in both Time Capsules, then power off all your network equipment and the NAS/streamer/iPad. After this, power the equipment on again in the following order:

1) The router Time Capsule (then wait 5 minutes)
2) The bridge Time Capsule
3) The Synology NAS
4) The NAIM streamer
5) The iPad

Does this help?

Unfortunately not.... All the devices also have fixed IP address. Should the minim server be visible ALL the time? Because after a few minutes it re-appears in the NAIM app.

I don't think it should make any difference that the devices have fixed IP addresses.

MinimServer should appear all the time. It sounds like the SSDP "alive" announcements that MinimServer sends out every few minutes are being received by the NAIM app but the SSDP M-SEARCH requests that the NAIM app is sending out aren't being received by MinimServer.

When MinimServer appears in the NAIM app after a few minutes, does it stay visible indefinitely or does it disappear after another few minutes?
