That doesn't explain why the PS3 isn't found though.Ī trace log from when both the PS3 and PS4 was turned on while UMS was capturing log could be interesting though. Maybe you should check the network configuration for the PS4 to make sure there is no NAT configured there. NAT should NOT be configured in the PS4, that would block network traffic to the PS4. Either it's read the router configuration via UPnP, and the router should run NAT, or NAT is somehow configured in the PS4 itself. The MP4 video is not compatible with the devices that installed Plex media server. The only thing I can see that I find a little bit strange is that the PS4 lists NAT to NAT type 2. To be specific, there are many situations that can lead to this issue, for example: 1. I have no idea why this doesn't work, maybe restarting the PS4 while UMS is running could help? I take it the Windows firewall is still off. UMS also finds your router on 192.168.2.1. It doesn't receive any further contact from 192.168.2.103 though. In the last log, UMS finds a device 192.168.2.103 which I assume is the PS4. The only thing I can find is that the IP of your server (192.168.2.101) mismatches with your screenshot (192.168.2.102), but I'm guessing that you have changed that since you took the screenshot.
