Fix: YouTube Comment Failed to Post

You may fail to comment on YouTube videos due to interference by your adblocking extension or a VPN. Moreover, the auto-generated YouTube user name may also stop you from posting comments on YouTube videos.

The affected user gets the error with a little circling icon when he tries to post a comment/reply of a comment on a YouTube video. In some cases, the user encounters the error when he tries to edit a posted comment/reply, and the published comment vanishes. Some users cannot see the comment after refreshing the page. This issue is not specific to a particular platform i.e. it can occur on Windows, Mac, or mobile devices.

Comment Failed to Post

In some rare occurrences, users face this error just on a single channel (whereas they can post normally on other channels). Some of the affected users were able to comment on live streams but not on the videos.

Before proceeding with the troubleshooting process, make sure you are using an updated version of the browser/app. Moreover, refresh the page continuously for 5 to 6 times and then try to post the comment. Also, relaunch the browser and then try to post the comment. Furthermore, launch the video directly when you want to post a comment (not through the notifications). Additionally, you can try another YouTube account in a new browser to rule out any browser/account issues. Also, make a habit of not commenting more than 2 or 3 comments on a single video.

Also, you must keep in mind that YouTube is continuously changing its policies to curb spam. If you are being suspected of spam, for example sharing URLs in your comments, posting the same comment on every video, or if you are posting comments continuously without any time gap, you may fail to post comments on YouTube.

Moreover, video uploaders also apply different settings about what can be posted in comments e.g. if a content creator has enabled the setting of only approve comments can be posted to a video, and your comment is not approved by the video uploader, then it will not be visible to others (but maybe shown to you).

Solution 1: Disable Your Adblocking Extension

You may not like Ads, but ads are the essential source of income for YouTube and that is why YouTube does not “like” Adblocking extensions. You may encounter the error at hand if you are using an adblocking extension. In this scenario, either disabling the extension or whitelisting YouTube in the settings of your adblocking extension may solve the problem. For illustration, we will discuss the process for Chrome.

  1. Open the Chrome browser and click on Vertical Ellipses (3 vertical dots) near the top right corner of the windows.
  2. Now hover over More Tools and then in the sub-menu shown, click on Extensions.
    Open Chrome Extensions
  3. Now find and disable Adblock extension.
    Disable a Chrome Extension
  4. Then open the YouTube website and check if it is clear of the error.
  5. You can also whitelist the website in your adblocking extension.

Solution 2: Disable Your VPN Client/Extension

It is a common norm in the IT industry to use VPN to bypass restrictions imposed by ISPs or sites. Moreover, VPN provides a great opportunity for a user to save his privacy from prying eyes. You may encounter the error under discussion (especially in case of a mobile app) if you are using a VPN client/extension to access YouTube because sites like YouTube or Netflix discourage the use of it. In this scenario, disabling the VPN client may solve the problem.

  1. Disable your VPN client or browser extension.
  2. Now launch browser/mobile app and check if you can post a comment of a YouTube video.

Solution 3: Re-Login to the YouTube Site

Cookies are used by sites to store client/server communications. A corrupt cookie can cause a lot of issues. The issue at hand could also be a result of a temporary glitch or corrupt cookie of the site. In this case, signing out and then signing back into the site may solve the problem. You can also try incognito/private mode.

  1. Open your browser and navigate to the YouTube website.
  2. Now, click on the user icon (near the top right corner of the window) and then click on Sign Out.
    Sign Out of YouTube
  3. Now close your browser and restart your system.
  4. Upon restart, launch browser and Open YouTube to check if you can comment on the videos

Solution 4: Change the Username for YouTube

There is a glitch on YouTube, in which, if the user name is auto-generated by the website, e.g., if your email ID is being used as the username, then you may encounter the error under discussion. In this scenario, changing your username may solve the problem.

  1. Change your username for YouTube.
    Change the Username for YouTube
  2. Then check if you can post comments on the YouTube videos.

Solution 5: Post the Comment after Playing the Video for Some Time

YouTube is making continuous efforts to stop spammers from posting comments. One such step is stopping the user from posting the comment on a video if the video was not played or played for just a few seconds. In this context, playing the video for at least one minute, and then posting the comment may solve the problem.

  1. Open YouTube and play the problematic video.
  2. Now let the video play for at least one minute (no forwarding) and then check if you can post the comment (without pausing the video).
    Playing video for a longer time
  3. If not, try to pause the video exactly at the time when you want to make the comment and then check if you can post the comment.

Solution 6: Try Another Browser

Every browser has its share of bugs. The issue you are encountering could be due to a temporary bug of the browser. In this context, using another browser to comment on the YouTube video may solve the problem.

  1. Download and install another browser (if not installed already).
    Download Chrome
  2. Now launch the newly installed browser and check if you can comment on YouTube video. For example, if you are having issues with Firefox, then try to use Chrome.

Solution 7: Try Another Platform

Along with the web version, YouTube can be accessed with the Andriod and iPhone applications. The current issue could be platform-specific e.g. the issue could be just on the web version of Windows. In this context, trying another platform to post comments on YouTube videos may solve the issue.

  1. If you are encountering the issue on a browser, then try a mobile app (Android app or iPhone app).
  2. If you are encountering the issue on a mobile app, then try the web version of YouTube.

For Mobile Applications:

Solution 1: Enable/Disable the Dark Theme of YouTube Mobile App

There is a reported bug in the YouTube mobile app, in which, dark mode (enabled or disabled) impacts a user’s ability to comment on the videos. In this context, enabling (or disabling) the dark mode may solve the problem.

  1. Open the YouTube mobile app and start playing a video (or problematic video).
  2. Now while playing the video, hit the back button (which will bring out your home screen, whereas the video is being played in minimized state at the bottom of the screen).
  3. Now tap on the user icon (near the top right corner of the video).
    Tap on the User Icon in the YouTube App
  4. Then tap on Settings.
    Open Settings of YouTube
  5. Now tap on General and then Enable (or Disable) the Dark Theme.
    Enable Dark Theme
  6. Now go back to the home screen.
  7. Now tap on the minimized video and then tap on the play button to play the video.
  8. Now tap on Comments and add a public comment to check if the problem is sorted out.
    Add a Public Comment to the Video

Solution 2: Reinstall the YouTube Mobile App

If you are encountering the issue on a mobile device, then most probably the corrupt installation of the YouTube application is causing the issue. In this scenario, uninstalling and then reinstalling the application may solve the issue. For illustration, we will discuss the process for the Android app.

  1. Open Settings of your phone.
  2. Now tap on Apps/Application Manager.
    Open Apps in Settings of Your Phone
  3. Now tap on YouTube and then tap on Uninstall.
    Uninstall YouTube
  4. After uninstalling the app, restart your device.
  5. Upon restart, reinstall the YouTube app and check if it is clear of the error.
  6. If there is no uninstall option available at step 4, then Force Stop the app and then tap on Storage.
    Force Stop the YouTube Application and Open Its Storage Settings
  7. Now Clear Cache and then Clear Data of the application.
    Clear Cache and Data of the YouTube Application
  8. Then tap on the back button.
  9. Now tap on the Disable button and restart your phone.
    Disable the YouTube Application
  10. Upon restart, enable the YouTube app (as discussed in the above steps) and then check if it is clear of the error.

If nothing has helped you so far, you can try TubeBuddy extension (or something similar) and use its notification center to post the comments/replies. You can post comments on YouTube videos by using the older layout of YouTube but since 2020, most tricks/workaround to load the old UI of YouTube has stopped working, so, you may or may not be able to load the older layout of the site.
