Hi dNoize
What do you get if you use the following url in a browser?
http://192.168.178.5:3689/server-info?output=xml
As the used ip is an internal ip address, I suppose you are only using silverPlay from within your local network.
if you want to use it from outside your network you have to provide the public ip 🙂
If the first command is working, can you try to add teh debug=true proeprty to the init parameters in the html file?
This will replace the mesh panel with debug output.
Hope that helps,
Manfred
