Comment failed to post on YouTube? Here's a quick fix

One of the great things about YouTube is that its users can usually leave comments under videos

However, a Comment failed to post error can arise for some users when they try to post a comment for a YouTube video.

Consequently, the comments some users enter don’t appear on YT pages.

How can I fix the comment failed to post on YouTube error?

1. Play the YouTube page’s video for a minute

To stop spamming, Google blocks comments from users who haven’t played videos on YT pages for at least a few seconds.

So, try playing the video on the YouTube page you can’t comment on for about a minute or two.

If you still can’t comment on YT pages after playing their videos, try the resolutions below.
