AssetUPnP 7.2 not working on Ubuntu Server 20.04

[mhirsch]

Hi,

I installed AssetUPnP on Ubuntu Server 20.04 running on a ASRock DeskMini X300 box. AssetUPnP is running, but it does not show up in the control point I am using (BubbleUPnP on a Samsung tablet). The web interface of AssetUPnP works. Also, it is sending out "alive" broadcasts, I checked this with "UPnP Analyzer", a small Mac app.

Sample broadcast (from AssetUPnP on Ubuntu):

NOTIFY * HTTP/1.1
Host: 239.255.255.250:1900
LOCATION: http://192.168.1.107:26125/DeviceDescription.xml
NTS: ssdp:alive
CACHE-CONTROL: max-age=1800
Server: UPnP/1.0, DLNADOC/1.50, AssetUPnP/1.0
USN: uuid:1D5BB7C1-A9A7-9D08-0-123456789abc::urn:microsoft.com:service:X_MS_Media ReceiverRegistrar:1
NT: urn:microsoft.com:service:X_MS_MediaReceiverRegist rar:1

I tried both the trial version of AssetUPnP and my registered version, with the same result (i.e. nothing shows up in the control point).

I have a Raspberry Pi on the same network running AssetUPnP 7.2 which works fine, i.e. it does show up in the control point and I can stream music from it. The broadcast messages from the Pi look almost the same as the ones from Ubuntu:

Sample broadcast (from Raspberry Pi):

NOTIFY * HTTP/1.1
Host: 239.255.255.250:1900
LOCATION: http://192.168.1.104:26125/DeviceDescription.xml
NTS: ssdp:alive
CACHE-CONTROL: max-age=1800
Server: UPnP/1.0, DLNADOC/1.50, AssetUPnP/1.0
USN: uuid:BB65EE48-EDEE-33C9-0-123456789abc
NT: uuid:BB65EE48-EDEE-33C9-0-123456789abc

I am at a loss why the Ubuntu version of AssetUPnP does not show up in the control point whereas the Raspberry Pi version does. Both devices are connected (via Ethernet) to different ports on the same switch.

Any hints are appreciated.

Thanks,

Michael

Try a different control point as a test:

Thanks for the hint. I tried AssetControl, the result is the same: AssetUPnP on Ubuntu does not show up, AssetUPnP on the Raspberry Pi does. I tried two more control points (mconnect on an iPhone and T+A Music Navigator on a Samsung tablet), again with the same result.

Thanks,

Michael

I have found the culprit - it is the WLAN base station (Netgear RBR850). For whatever reason it is not passing some UPnP packets between the LAN and WLAN part of my network. The Pi did work because it was on the WLAN too, something I did not realise initially. The workaround is to create a second WLAN with a different base station that does not have the problem, just for the control points. With the WLAN created by my ancient ADSL router / WLAN base station from Swisscom AssetUPnP on the Pi and on the Ubuntu box shows up in the control points (Bubble UPnP, mconnect) and streaming works fine.
