Hello, nineninesixteensixteen!
Thanks for using Apple Support Communities! If we understand correctly, you're trying to view videos on your iPhone, but it is giving an error during playback. We love watching our videos and want to help get yours playing again!
To better understand and help others answer your question, reply with the following details:
- Are you connected to Wi-Fi or cellular data? Does this happen when using another reliable network?
- Can you watch other videos through the Photos app?
- If you restart your iPhone, do the videos play as expected?
Best wishes!
