I can't watch videos on my iPhone 4S?

I can't seem to watch videos on my iPhone. When I try to watch a video on YouTube for example it just says 'playback error tap to retry'. None of the videos I watch load, I have this problem general videos on the internet, not only on YouTube and also on Instagram.

So far I have tried resetting my network settings and rebooting my phone but nothing seems to work. I don't know what could be the problem.

Did you by chance update the iOS recently? I updated and since then I'm having the same problem. I get a new problem with every update.
