"Can't play video" error

[AC Question]

I can't play any video on my huwawei honor phone. I think it's not just because of the format of the video because even on websites, still the videos won't play at all. How can I fix this please?

I fixed the problem of videos not playing in YouTube and Facebook by simply restarting the phone. (After trying 100 other things before) Worked like a charm!
