[PROBLEM] UPnP Client not discoverable after a period of time

[RafaPolit]

I have just replied in 3 threads concerning problems with Moode 5.2 and UPnP in several different fronts.

I do think this needs to be addressed, as it does not seem like an isolated incident anymore.

Try reverting to kernel 4.14.98 or bumping to 4.19.42.

Code:

# 4.19.42 (patch 413e9a2)
echo "y" | sudo PRUNE_MODULES=1 rpi-update 413e9a212ee40a0a2506b403915598a74a90f3ef

# 4.19.40 (moOde 5.2 default)
echo "y" | sudo PRUNE_MODULES=1 rpi-update 6cb1da772a8c56f44591bec904046b15f1126949

# 4.19.34 (moOde 5.0/1 default)
echo "y" | sudo PRUNE_MODULES=1 rpi-update 99c274691c07480762dcda91a0ebfe3c4f519307

# 4.14.98 (slightly later version than one used in moOde 4.4)
echo "y" | sudo PRUNE_MODULES=1 rpi-update a08ece3d48c3c40bf1b501772af9933249c11c5b

# cleanup
sudo rm -rf /lib/modules.bak
sudo rm -rf /boot.bak
sudo apt-get clean

sudo reboot

I'm bumping to 4.19.42. I'll report back tomorrow with any progress.

[bump_here]

Sorry been away with work. Bumping the kernel doesn't seem to have made any difference.

I'll try reverting.

[bump_here]

Rolling back doesn't seem to have solved it.

FWIW I'm not seeing the same issues on the Pi 3 B+ I have in the lounge. Wondering if it's something related to the Pi 2? Any thoughts?

[TheOldPresbyope]

I haven't been able to repro but I've been working only with RPi3s. 

I suppose I have an RPi2B in some project or another which could be repurposed for testing the UPNP subsystem.

How is your RPi2B connected to your network? Ethernet? USB/WiFi adapter?

It's an ethernet connection on the 2B

Sorry, I've been out and about celebrating the graduation of my twin grandkids and their friends from high school. 

In the meantime, the RPi2B I set up with stock moOde 5.2 and connected via Ethernet to my LAN has been running for 7 days with its UPnP Client for MPD enabled.

I hacked a script which checked several times a day that this moOde player's UPnP renderer is discoverable on a second computer (connected to the LAN wirelessly as it happens). 

As well, whenever I was able I used several apps such as BubbleUPnP on an Android phone and Linn Kazoo /Linn Kinsky on an iPad to test that I could still connect with and control the moOde UPnP renderer. 

It all just worked and I still don't know why the interruption to service you are experiencing occurs.

Kent

I never got an interruption either. Could it be that the router is renewing IPs or something else outside the PI and more having to do withe the network infrastructure?

.... Could it be that the router is renewing IPs ....
Rafa.

Ooh, I like that hypothesis!
