Renderer not found, access granted(upnp,no I/O server worker)

[h8spaCec4EspUdE]

I have trouble on renderer recognition:

win7 x86 sp1, ums5.0, panasonic tv
1. access granted with UPNPHelper
2. no I/O server worker socket follow up > recognition process does not start (Renderer not found)
(However, in rare cases, I/O server worker socket is received . Then, panansonic tv is recognized.)

I have tried other dlna servers. They can be recognized by the tv quickly.
Firewall setting is checked, I think the problem is no I/O server worker socket received.
I also noticed in the Panasonic-Viera.conf file, there exists a line:
UpnpDetailsSearch = Panasonic

Is it possible to edit it to enable recognition through upnp?
Or in rare cases, the tv is recognized. Then, I saved the profile and found:
device = 192.168.0.101

Can I bind this ip to panasonic tv profile so the recognition process can be quick, and does not need to rely on I/O server worker socket.

Is it because the tv does not recognize the ums upnphelper message as a dlna media server. Therefore, it does not send back user-agent message for I/O server worker?

When I use plex server, the log showed that user agent header was received.
However, at the same time, ums received nothing.
Could anyone suggest a solution?
