If you're reading this article, chances are the Roblox app or website isn't working for you right now (same here) and you're wondering why—is this an internal issue with your PC or phone, or is Roblox experiencing a global server outage that's out of your control? More often than not, the latter is the culprit, meaning that it's up to the tech wizards at Roblox to find the disruption and fix it as soon as possible. Even with this knowledge, however, you may still be wondering what exactly happened at Roblox HQ, and while I can't say for sure, I've detailed some of the possible causes of this outage in the guide below.
Why is Roblox down?
UPDATE: Roblox appears to down as of May, 15, 2023 at 1:30pm CT - Error Code 529 - Players are experiencing an error when attempting to join games
Error Code: 503
A 503 Service Unavailable Error typically occurs when the site you're trying to reach is unable to complete your transfer request or, in other words, can't successfully lead you to where you want to go. This can happen for multiple reasons, but the most common instances are either the website is receiving too many users attempting to access it at one time, or it's been taken down by the site admins for maintenance. In the case of Roblox, considering the platform's massive popularity, either of these possibilities could be causing the 503 Error.
More often than not, this error is not fixable by the user, meaning that it's just a waiting game until Roblox gets things up and running.
400 Bad Request Error
To put it simply, a Bad Request error appears when a user is trying to access a Roblox page and the Roblox servers read the request as invalid or incorrect. Because of this, the request fails. This error often appears because the content that you're trying to reach no longer exists, meaning there's no valid or correct page to access.
In some cases, however, the Roblox servers experience an issue that causes all requests to be read incorrectly. When this happens, every page that a user attempts to access is falsely labeled as invalid and is no longer accessible. Unfortunately, only Roblox can fix this issue—there's nothing that can be done from a user perspective to help the situation.

Error Code: 529
Whether you run into "An http error has occurred. Close the client and try again. (Error code: 529)" or "We are experiencing technical difficulties. Please try again later. (Error code: 529)," a 529 error typically relates to the status of Roblox itself, not the individual user. This means that, oftentimes, the issue is much more widespread and is affecting more than just your device—players around the globe are likely running into the same issue. To put it simply, a 529 error normally means that the Roblox servers are running slower than usual or are completely down.
Typically, this type of error can unfortunately not be fixed by the user—instead, your best bet is to regularly check the Roblox status page, which monitors statuses across the entirety of Roblox and updates accordingly when issues occur. There are cases, however, where this error comes to you as a glitch. If you believe that your internet connection is causing the 529 error, we'd suggest disconnecting and reconnecting to your wifi and then restarting your router. You could also try logging out of Roblox, waiting a bit of time, and then logging back in.
Error Code: 524
Similar to the other error codes in this guide, a 524 error code often cannot be fixed by the user, and must instead be fixed by Roblox itself. Typically, players run into 524 errors when the site is down for scheduled maintenance, but it can also occur due to unscheduled down time as well, such as a server crash. This error can also appear when players attempt to join an experience that they're blocked from, such as a non-VIP user attempting to join a VIP-blocked experience.
When will Roblox be back up?
Though we never have the exact answer to this question, we can say that if Roblox is currently down, we can assure that progress is being made right now to fix the issue. Within 30 minutes, a Roblox outage is typically taken from global to individual users, so you should be seeing a total fix within the next few hours at most. Considering the chaos that ensued during October's massive outage, Roblox is likely extremely prepared to handle any kind of server issues moving forward, including the one that you're currently facing.
If you feel as though your inability to connect to Roblox is persisting past what other players are experiencing, however, we'd recommend reaching out to Roblox support directly and discussing your personal connection issue with a member of their team.
