Fix YouTube Comment Failed to Post Issue or Unknown Error

YouTube allows its users to interact on the platform through the comments section. You can post questions, appreciations, or anything you want to say. However, many users face an error after they try posting and sending a comment.

When a user hits the Enter to send a comment, the loading process takes time and ends up showing the error message, “Comment Failed to Post” or “Unknown Error” when using an old format. This problem happens on any video even if the user actually owns the video he is commenting on.
