Exclamation [Q] Shifting media when using Skifta app not working

OK , first off thanks to everyone who helps me with this problem just so you know I did work very hard to try and resolve the issue on my own.
Problem: my computer is not at my house and while I'm at home I can shift media from my computer to my phone using the Skifta application over my LTE network just fine but when I try to shift it to my bluray it gives me the error "unable to determine what media types the media player supports". Now I was able to shift to the bluray player perfectly fine right before I rooted my device . I use T-Mobile and did do the tethering block fix on my device . any and all help will be much appreciated!!
