Problems with altered apps, such as Vanced, are typically the result of an app fault or Google account services. Most of the time, all it takes to resolve the problem is a quick device restart or an app cache clean. However, there is more to fix when dealing with Youtube Vanced Error 400, and here are some troubleshooting techniques to help.

Fix: Youtube Vanced Error 400 and Can’t Login Error

When the program encounters error 400, it typically indicates a server connection issue with YouTube. This may occur due to two factors: either Vanced’s ability to retrieve data from Youtube servers has stopped working, or your device is not receiving stable internet service. Here are a few pointers to get things going.

Restart Device

The team behind Youtube Vanced, a modified application, is comparatively small. As a result, the program has a few small flaws and performance problems with RAM and memory usage.

As a result, error notifications will inevitably appear; however, a simple device restart will resolve them all. Restarting your smartphone will free up RAM and unused CPU power, enabling the app to function properly and preventing problems down the road.

Check Internet Connection

In essence, Youtube Vanced Error 400 is a server error that shows that the application was unable to establish a relationship with the server. It could be the result of a shaky or unreliable internet connection. In order to run online videos, please check with your internet provider to see if you have a stable internet speed and a functional internet connection.

Check your date and time settings

Every program that makes use of the internet must have up-to-current time and date information on its devices. If there are problems with the date on your device, Youtube Vanced won’t function.

Navigate to the Date & Time settings on your smartphone by opening the Settings app.

Here, select your area and confirm that you have enabled the automatic update.

Check your date and time settings

Disable VPN

You can connect to servers and regions on other continents with a VPN. However, since VPNs add another layer to internet routing, slowing down apps and services, they are not always necessary to use. You may occasionally see error 400 if your internet is sluggish or if the VPN server is down. Therefore, if you’re using any VPN programs, disable them.

Navigate to the Network & internet option on your smartphone by opening the Settings app.

Vanced was recently forced to close due to many legal threats from Google. This means that there won’t be any more Vanced app updates and that all current development on the app is ending. The app functions properly, albeit it won’t be long before it stops as well.

Therefore, we advise you to try other free YouTube mod applications like OG Youtube that offer comparable functionality if none of the aforementioned ways work for you.


The Youtube Vanced error 400 and the inability to log in error can be resolved in a few different methods. Despite the fact that Vanced has been discontinued for legal reasons, the software continues to function properly.
