What causes this issue?
The main cause that triggers this issue is the Restricted Mode. When this option is activated from the Settings of YouTube, the issue appears. But there are cases when the issue has appeared even if the option was disabled. It might also be affected by some cache files which have become corrupted. These files don’t affect the app directly but can cause problems when too many cache files gather in your phone. This issue could also appear when YouTube doesn’t have the permission that it needs to work. Another cause could be your internet connection, causing issues like this one when the connection is not strong enough.
How to fix the YouTube Server Error 400?
There are a few methods that you could do to fix this issue. All of them can be easily done from your phone, so here’s the list that you need to follow:
1. Disable the Restricted Mode
The first thing you need to do is to disable the Restricted Mode on your YouTube account. This is an optional setting that YouTube has which should hide and block the potentially mature content on the platform when activated. This option can be found in the General section of your YouTube Settings. You could’ve enabled this option by mistake, or someone else that has access to your account. All you need to do is to disable it to see if this is what causes the error for you. Here are the steps you need to follow:
2. Clear the data and cache files
This error might be also caused by some cache and data files that YouTube is storing inside your phone. These files appear when you open the app and they should reduce the loading process. But these files might become harmful in time, affecting the app. All you need to do is to go to the Settings of your phone and clear the data and cache files. This process won’t affect the app because these files are temporary. Here’s a guide that will show you how to do this:
3. Give Permission for YouTube
You should also ensure that YouTube has all the Permissions that it needs to work. When you first launch the app, YouTube requests a few permissions to be able to run. Some permissions might’ve been denied without realizing it, which might trigger this issue now. All you need to do is to go to the Settings of your phone and give permission for YouTube. You should enable all the permissions to see if that fixes the YouTube Server Error 400. Here are the steps you need to follow:
4. Reset the Date & Time
Another cause for this issue could be a simple error triggered by your phone. You should also try to reset the Date & Time to see if that fixes your issues. You can do this from the Settings on your phone. All you need to do is to change the date and time, then put them back to the default. Here’s how you can do this:
5. Update YouTube
The YouTube Server Error 400 could be also by the app being outdated. This can happen when the auto-update option is disabled, or you don’t have enough free space to install the update. When the app is outdated, many errors could appear because it is not running on the latest version. To install the latest update, you need to go to Play Store and search for YouTube. Here are the steps on how to do this:
