What Are The Causes Of HTTP Error 503?

It is difficult to figure out the cause of this error just like it is with “502 bad gateway error” or “500 internal server error”. 

  • The major culprit for this error is a failure in the connection between the server and the web page you’re trying to access, making it unable to process any requests from users through their browser. 
  • The server might be going through some regular maintenance, which can cause it to be shut down temporarily.
  • The server might be getting a lot of information requests from many users at the same time. This situation can cause the server to have issues while trying to bring up said information. This most commonly happens with a small website whose servers aren’t well equipped for handling a big influx of user requests at the same time.

How to Fix HTTP Error 503

  1. Try refreshing the page a few times. Alternatively, you can try resetting your router.
  2. If you’re using a proxy or a DNS/VPN and see the error “Service Unavailable – DNS Failure,” there may be something wrong with your DNS configuration or VPN. Try different DNS settings or switch the DNS configuration back to default; try turning off your VPN.
  3. If the issue is caused when the user count of the website peaks, it may be wise to increase the server’s resources to accommodate the high number of users.
  4. If the error is caused by a DoS (Denial of service) attack, you should contact the host of the webpage and see what can be done to prevent things such as this from happening again. The host might want to increase the security measures used or pursue legal options.
