This is an amazing app. A lot of the posts on here are quite confusing as they keep mentioning support for ubuntu and what not. Since im a windows user ive finally got it working on 3G connection.
Make sure u got the port forwarded for 1978
And also add in the ports range from 19780 - 19785.
I found the Tablet Browser method the best to use for the transcoding profile as there was no lag and the player responded more quickly wen needed to be stopped.
Gna test it again to see if it works again.
