  1. Clear the app's Cookies, together with its Cache from your browser; In some scenarios, the error sometimes occurs due to your browser attempting to make use of an item that has already been cached. Therefore, clearing every cache on your browser might help remove this function failure code. You not only need to clear caches, but you also need to clear all browser cookies. By all, we mean, you must leave no cache or cookies on your browser. To delete all cookies and Cache, select the tab “The beginning of time”.

  2. Clear YouTube Cookies on your Browser: Rather than taking the previous step initially, you should try clearing all YouTube-related cookies first. Clearing all cookies on your browser means you get to lose everything saved on your browser, including your passwords and login details. For this reason, you should try this before carrying out the step above. The only sure disadvantage of this is that it logs you out of YouTube, aside from that, this step works for most devices.

  3. Switch your browser to the Incognito mode: When the disruption occurs, you should try going incognito or resetting your browser settings. The incognito mode option can be found in the menu bar. However, to reset your browser settings,

  • Click on Settings in the Menu tab

  • Scroll to the bottom of the settings tab where you will find the button “Advanced options” and click on it.

  • Under this tab, you will find the Privacy and Security option. Click on it as it will lead to the Content Settings tab.

  • Scroll to “Cookies” and click on it. This shows your general cookies so you have to search for YouTube cookies.

  • When the search result appears, click on “Remove all” and confirm the action.

  • Exit the browser and restart your system.

4. Use the video ID in place of its link: If you come across the "400" error code while searching for a video with its link, you should try the search using the video ID instead. Getting the video ID of the video you would like to watch is not difficult. All you have to do is,

  • Visit the YouTube webpage where you will find the URL of the page.

  • At the end of the URL, there is an equal sign (=). The combination of letters and numbers placed after the equal sign is the video ID. You can copy that to make your search instead.

5. Uninstall and Reinstall Chrome: Although highly rare, if the code 400 remains after you have taken the four steps already mentioned, you should try reinstalling your chrome browser.

You could also try troubleshooting the error as a 504 Gateway Timeout problem.
