No compatible files found?

I have a my book live which I have used without issue for years to stream movies for my kids, however in the past couple of days when accessing it via my TV it doesn’t show any of the folders and just states no compatible files found. It does this whether I select video, photo or music. I tried through the Roku streaming boxes we have in other rooms and get the same result. I’ve tried resetting etc. but am still able to access the drive from my phone, so am at a complete loss as to why I cannot now access the drive through my TV. Any ideas?
Please note, I no longer have a computer as I use my work laptop and it has windows 10 so won’t allow me to access remote drives at all. I therefore manage all of my files via my phone or iPad. Thanks
