In this article, we will discuss the reasons for YouTube Error 503 and how to correct it.
What does “error 503” mean?
While watching YouTube videos, many users sometimes come across Error 503 – service unavailable. Often this happens when accessing a work resource more recently, so the situation can be very annoying. This code informs that the resource is temporarily unavailable, and the keyword here is “temporarily”. In simple terms, this is a kind of plug of an empty page, where the user ends up.
Each account on the server is assigned a certain number of worker processes that process user requests. Requests are sent to the server and queued. Light requests are processed quickly, and heavy, problematic ones – slowly, slowing down the progress of the queue. When the queue reaches a certain length, the server stops accepting new requests, returning a 503 error.
The error can occur on YouTube regardless of the user’s device: laptop, tablet, or smartphone. There are the following reasons:
● Server problems. It also includes incorrect scripts, poor code optimization, and database error. In this case, just need to check the server status regularly.
● The connection timed out. It occurs when the APN settings have been changed from their default values.
● Problems related to the browser, the extensions, and the plugins installed on it. They stop performing the required functions or conflict with other plugins.
● Transferring (or processing) large files on the server leads to the freezing of site scripts and slows down the work.
● A significant number of users trying to log in at the same time – sometimes such situations are created deliberately in order to disable the site.
● YouTube user account issues.
In most cases, users report that the error arises when they click a video from the Watch Later list. What’s odd about this issue is the fact that if a user tries to view the same video from a regular search, it usually plays without errors.
Ways to solve it
In order to fix this issue firstly, it is recommended to try to refresh the page – it seems obvious, but since 503 errors are often caused by a congested network, simply refreshing the page might fix the problem.
If it doesn’t help there are several methods to solve this problem:
● Check the status of Google servers. To make sure the issue is not server-related, you need to visit websites such as DownDetector or Outage to see if other users like you are experiencing the same issue. Another good place to search is the official Twitter account on YouTube.
● Removing a video from the Watch Later list. Mostly, the error happens for users who have added a lot of videos to the Watch Later list.
● Clearing YouTube cache data. Corrupted and outdated cache files can also cause the problem.
● Restarting the browser.
● Updating Adobe Flash Player.
● The error is corrected by resetting the settings. To do this, you need to clear the cache and data. You also need to restart WI-FI.
