HELP! My phone will no longer play any videos

[appleclem]

I've recently got a new HTC One. I've had it for around a month now and has been working perfectly. But the other day I was watching something on 4OD, it worked for ten minutes and then stopped saying "Sorry this video cannot be played.". I then assumed it was a problem with 4OD so started using iPlayer which worked fine until about half an hour into my programme when the same message came up. Since then I have not been able to watch YouTube, Vine or Snapchat videos. Someone help!!

OK let's start with the obvious here. Have you restarted the phone? You can also simulate a battery pull by holding volume up then the power button until it shuts off just incase you need to. What kind of connection are you using when this happens, 3G, 4G, wifi?
