Reddit Error Code Fix | 503, 504, 403, 405, CDN Unable to Reach

Reddit error code fix is exactly what you need when being faced by one (or more) of the pesky 503504403405, or “Our CDN was unable to reach our servers” messages. As the self-proclaimed “front page of the internet,” it’s obviously a massively big deal when users can’t access the latest news, memes, and other must-see content. The world would presumably fall apart with lengthy Reddit downtime, and so any maintenance or unscheduled offline periods are best avoided. Here’s what you need to know about Reddit error code fixes.

Reddit Error Code List and Fixes

Reddit Error Code Fix

Reddit downtime isn’t always caused by the same issue. This is why there are a variety of error codes assigned to different problems. Unfortunately, those error codes aren’t exactly clear when it comes to explaining why Reddit is down. Below is a list of the error codes you may see when Reddit is suffering from a period of downtime, as well as suggestions for potential fixes.

Reddit 503 error code fix

The Reddit 503 code appears with a “service unavailable” error message. This happens when you try to visit a page, but it fails. In the case of Reddit, this can happen when the website has too many visitors. Extreme levels of traffic is no doubt a big problem for Reddit, as the site often hosts threads that become extremely popular through external links and social shares.

As for how to fix the Reddit 503 error code, there are a few things that you can try on your end:

  • Refresh the page you are trying to view.
  • Wait for a few minutes and try refreshing the page.
  • View other pages while waiting, as the 503 code will often only appear on the more popular threads.

Reddit 504 error code fix

The Reddit 504 code can be experienced due to a “gateway timeout.” This is where the server does not receive a quick enough response for the page content to load. Similar to the 503 code, this error can pop up when Reddit is too busy.

The common Reddit 504 fixes are as follows:

  • Refresh the page you are trying to view.
  • Wait for a few minutes and try refreshing the page.
  • View other pages while waiting. (Signing out or changing accounts seems to help here.)



Reddit 403 error code fix

The Reddit 403 code most commonly appears when the user is banned from the subreddit that they are trying to access. A “Forbidden” message accompanies the code, offering a pretty clear indication that the user is not permitted to enter that page.

If you know a reason why you could be banned from the subreddit you’re attempting to access, then it’s likely that a moderator has added a ban to your account. However, if you’re seeing this without a warning from a moderator, you’ll be wanting to try and make contact.

Reddit 405 error code fix

As with other 4XX messages, the Reddit 405 error code is likely down to an error on the user’s side. Specifically, the Reddit 405 code comes accompanied with a “Method not allowed” message. It often appears when the user is attempting to view a page on mobile using the “compact” version of the site. Mobile Firefox is especially prone to displaying this Reddit error.

If you’re looking for a Reddit 405 fix, then you’ll want to attempt the following:

  • Try viewing the page in “Desktop Mode,” if your mobile browser allows for it.
  • Try using a different mobile browser, especially if you’re currently using Firefox.
  • If all else fails, you can bookmark the page for viewing later on a desktop.

Reddit “Our CDN was unable to reach our servers”

As noted in our dedicated guide, the Reddit “Our CDN was unable to reach our servers” error message is a particularly nasty problem to run into, as it seems to affect the entire website. On the bright side, this isn’t an issue on your end. It’s a problem with Reddit’s backend and servers.

Unfortunately, as this isn’t a problem that you can fix, the only solution is to wait until Reddit is back online.
