Devices disappear after ~1-2 Minutes

[IT-Lueg]

Airconnect runs on a Raspberry Pi 3B.
When I restart the service (service airconnect restart) I see my Sonos speakers on my iPhone.

The service runs with the following settings...

[Unit]
Description=AirUPnP bridge
After=network-online.target
Wants=network-online.target

[Service]
Type=forking
ExecStart=/var/lib/airconnect/airupnp-arm -l 1000:2000 -z -f /var/log/airupnp.log
Restart=on-failure
RestartSec=30

[Install]
WantedBy=multi-user.target

But after ~1-2 minutes the devices simply disappear again.

I use a unifi network.
IT looks like this...

UPnP is enabled

mDNS is enabled

Multicast is enabled on my APs

and I tried it with IGMP-Snooping On & Off

This is my Log...

airupnp.log

What am I doing wrong ???

Your players (especially Esszimmer) explicitely send a UPnP disconnect, so AirConnect removes them. I Don't know why they do that

[IT-Lueg]

Is it this ?

They're all Sono's speakers.
"Esszimmer" is a Sonos-Playbar.

Is there any way to do something about it?

[IT-Lueg]

And if "Esszimmer" sends a UPnP disconnect, why do all devices disapear ?

I’ve not looked at the log in full details, but they all seem to disappear at some point

[IT-Lueg]

Can you take a closer look at it as soon as you have time?

Today I will try to turn off the device "Esszimmer" and test if it works.

[IT-Lueg]

soooo... I unplugged the "Esszimmer" Speaker and tried it again.

If i restart the Service everything works.
But after some time all the Speakers disappear.

I created a new (smaller) log.
Can you please look into it ?

airupnp.log

That log simply shows a set of working stream session. I only can think of a problem with your wifi router which drops multicast requests / responses

@IT-Lueg I think it's the IGMP snooping on Unifi equipment. Try turning it off again, and then restarting your Sonos. It might work after that.
