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. 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.
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.
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.
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.
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.
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.
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.
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.
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. 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.
