Mezzmo client (Nexus 9) not finding server intermittently

[runf]

I hope I can make this clear. Mezzmo runs on my PC. I try to access it via the Mezzmo software on my Nexus 9 (and Nexus 4). When it connects it's perfect but most of the time it doesn't connect.
I have a very good internet connection on all devices all the time. All my devices, wired and wireless are recognized by my (new) router, the asus RT-AC53U. On the Nexus 9, in the Mezzmo list of servers, there will be the Nexus 9 (itself) listed only. I'll refresh and refresh and nothing happens, then at some point later it will show the Nexus 9 and my other devices out of the blue and I'll be up and running. All my devices are listed in media devices in Mezzmo on my PC..
I've tried just about everything in the faq. I had Mezzmo working pretty flawlessly on my now defunct Netgear router.
To try and sum up, My Nexus 9 connects to my wireless network just fine. Web, HBO go, you name it. But the Nexus 9 (and Nexus 4) will only find the server whenever it wants to or whenever the moon is full.
Ahhhh! It just happened! While I have been typing this the Mezzmo server screen on my nexus 9 went from only showing the Nexus 9 to showing the Nexus server (and windows media player). Now it will stream movies just fine!
Why not all the time?
Thanks.

Just to explain - your DLNA/UPnP devices and software programs (like Mezzmo Windows and Mezzmo Android) all talk to each other from time-to-time via UPnP/DLNA messages and this is how they know about each other. If a firewall or router setting blocks these messages, then you will experience the problem you are having - i.e. Mezzmo server or your devices not getting listed. Given that you have replaced your router and then these problems started happening, then it is most likely a (new) router setting.

Two things you can try in Mezzmo server:


Go to the Media Server Settings dialog and rename your Mezzmo server from "Mezzmo" to something else (e.g. "Mezzmo Llbrary") and click OK. Renaming your Mezzmo server forces your Mezzmo server Windows service to be re-registered in Windows and it may help clear out possible blocking that may be occurring in Windows.
Mezzmo server broadcasts its DLNA/UPnP messages at specific intervals. The default is every 30 minutes. You can try shortening the interval so that your devices and Mezzmo Android list it faster. See this FAQ - http://forum.conceiva.com/showthread.php/6245-FAQ-Change-the-default-SSDP-advertisement-interval. Try setting the interval to 60 (= 60 seconds).
