VTT preview thumbnails not working

I've made .vtt file like this:
added it to jw player as
tracks: [{
file: "",
kind: "thumbnails"
and on my vtt-server i see that jwplayer fetch it, but then even not trying to get images or crossdomain.xml (it is on that server).

What may be wrong in this vtt-file?

Hi, there!

Are the jpg’s you’re referencing in your VTT in the same directory as the VTT file?

Also, Mark is right, in order to figure this out, I’m going to need you to supply a link to a page where you have this all setup on.
