My JRMC28 is installed in a docker that has worked flawlessly for ages.
The DLNA server has worked fine and I could see all other DLNA renderers around the house (Marantz NA6006, Volumio... etc.) when I refresh zones on the Android JRemote on my smartphone.
For some unknown reason, since yesterday afternoon, nothing shows up in the available zones anymore.
All was working earlier in the day, I went out to get lunch, and came back and wanted to play music and there was nothing to see anymore, all the zones gone, except for Player and This device (The android tablet)
I thought it might probably be because of the old JRiver version, so I removed MC28 and updated to MC30, but alas, no joy...
I have been using this DLNA thing since I think MC24, so I am not really a newbie...
There is no firewall in my network at home and none of the renderers run on Windows OS...
Not sure what I really need to be doing... maybe someone has suggestions or ideas.
Thanks.

Did you try rebooting everything?
-
Yes, in fact, I wiped and re-installed one of the volumio mini PCs for example, and the Marantz was powered down / up a few times... I was literally in denial that it could be MC28... it has worked flawlessly for years...
But then I realised that all the other devices could not be all broken at exactly the same time, then decided to try another version to see if it will help.

First determine for certain whether it's a general network issue or if disappearing zones are only associated with JRiver. For example:
1) Try another Android player app, independent of JRiver, such as "BubbleUPnP for DLNA/Chromecast", and look at its list of detected Renderers and Libraries.
2) Use an Android network app, such as "Ping & Net", to do a Subnet Scan for a list of visible network devices.
3) Log into your router as administrator and see if the renderers show up as available devices. Have they always had the same reserved IP addresses (preferred), or are the assigned addresses free to change?
4) Is there a Windows update sitting around somewhere, waiting to be installed? If so, install it and reboot. (Any updates pending for the docker? the router firmware?)
Re MC Server itself, I am not familiar with Docker installs, but here is what I would check on a normal PC MC Server install:
5) Confirm the Media Center Service is running in the background (a different process than "Media Center xx" which runs the GUI). It should be visible under Task Manager. Within MC, look at Org Tree > Services & Plugins > Media Network > Server & Activity Log. You should see several different servers running along with their active logs.
6) Do the devices appear in Organization Tree under Playing Now as available zones? If they don't show up on the server, then most JRiver apps will not see them (Bubble is an exception since it does not depend on MC Server's Playing Now for its network devices info).
7) Are any zones "hidden"? Org. Tree > Playing Now > RMB Player > Show / Hide Zone > ...

I have the same problem. Were you able to figure this out…?

None of my wifi (DLNA, UPnP) devices show up under ‘Playing Now’. Therefore there has to be another reason why that would be, for a step #6 failure, when all other steps check out…

There are two parts to Playing Now. Renderers above and Servers below (may need to be expanded). Wiki for more details.
It can take a minute or two for devices to populate.
But you may have a problem caused by a firewall or antivirus.
Ports must be open. 52100 to 52200. And 1900 is also required for SSDP (discovery). It's on the wiki.

Thanks for your response, Jim…
The biggest mystery is that I installed MC33 in mid-January, and it’s been working fine until recently. If anything is coincidental, it was MC updating itself automatically last week to build 71.
JRemote is working fine with the current MC server, whereas the only problem seems to be the visibility of DLNA/UPnP devices on my LAN. Further, when I had posted here initially (MC33 forum), my streamer could see the MC server while JRemote could not see the WiiM. Now, and after I had redefined my MC server, the streamer now cannot find the server.
Right now, I’m at a loss as to what questions to ask. It’s difficult to point at JRiver, more like it’s something systematic—for example, my firewall, except turning it off solves nothing nor is it reporting blocking anything that I could create an exception for.
Are the ports you mention associated specifically with the MC server, or are they ports generally associated with protocols for accessing DLNA?
Cheers…

52199 is essential. It's JRiver's default port for Media Server.
1900 is not just JRiver. https://en.wikipedia.org/wiki/Simple_Service_Discovery_Protocol

To see a list of all ports which MC's servers are using:
Organization Tree > Services & Plug-ins > Media Network > Server (all servers) > Ports:
Also, for each individual server in the dropdown menu, it lists which specific port that server is using. On my system it lists
Port 52199 for the Library Server
Port 1900 is used by the Device Discovery server (SSDP)
Port 52100 is DLNA Media Server: [Server Name] (Generic DLNA). This one is setup in Options > Media Network > Add or configure DLNA Servers...
In the same window, the SSDP (Device Discovery) tab has a list of devices and their IP Addresses presumably known to MC. It has a Rescan button. Is that list fully populated as expected based on other views of your network?
-
Media Center can also use port 52200 for Media/Library Server if you have the SSL option enabled.

If JRemote can see, select and play from the server, these ports must be open, correct?
Also, a possible clue (?). I just noticed I’m not able to list the streaming possibilities from within Standard view. That is, if I select “Streaming”, nothing shows on the right (except “loading”). However, I am able to scroll down and select from the possible streams (e.g., Radio Paradise), select it, and choose “mellow mode” from RP’s own GUI

according to my ESET firewall, SSDP (port 1900) is, and has been, enabled. The mystery continues...

I succumbed to my desperation, and rolled MC back to v31 and, as you can see, my wifi devices have been restored under playing now and, more importantly, my WiiM is now showing as a zone in JRemote.
Please advise as to updating to MC33...
Edit: I initially only wanted to rollback to an earlier stable version of MC33, but I had forgotten which version I thought I remembered having been originally installed (30- something). That is, my memory isn’t perfect but I was sure all this began happening after MC auto-updated to v.33.0.71. How would you advise me for safely updating from 31 to 33?

This has to be a configuration problem. Probably the firewall or antivirus.
-
Yeah, my guess would be firewall.
