In some situations, the web server running your application may cause the problem. Your router's gateway will intercept it and perform the communication between your computer and the remote server on your behalf.
Problems arise when your computer attempts to connect to an IP address outside of this base range. In most cases, communication from one such local network address to another local network address is allowed. Your local home network, which is likely set up through a router (or router+modem hybrid), typically assigns IP addresses to all the devices on your network using the base address of 192.168.1.*, where the asterisk changes depending on the device. A gateway acts as a node within the larger network web, connecting and routing communications between multiple clients, servers, and other nodes within the (virtual) vicinity.īelieve it or not, most homes with Internet access have an active gateway. The gateway acts as, well, a gateway by which messages from the client are securely sent to the server, and vice-versa. In most HTTP communications, a client will connect to a server via a third-party gateway computer. Let's take a moment to discuss what a gateway (or proxy) is. The server providing the 504 Gateway Timeout Error is acting as a gateway. Diagnosing a 504 Gateway Timeout ErrorĪs mentioned before, a 504 Error means that a server upstream did not receive a "timely" response from another server further along upstream. If you have the capability, create a complete copy of the application onto a secondary staging server that isn't "live.” This will create a safe environment to test possible solutions to the problem, without jeopardizing your live application.

As such, it is critical that you perform a full backup of your application and database before attempting any fixes. Start With a Thorough Application BackupĪs with anything, it's better to be safe than sorry. However, a 504 Gateway Timeout Error could still occur if an upstream server is experiencing problems. Instead, it's possible that every aspect of your particular application (along with its servers) are working flawlessly.
The problem may not be with the specific web server your application is running on. Instead, it will be something on the server-side. If a 504 Gateway Timeout Error occurs, the issue isn't related to the app installed on your phone or local testing device. Many web applications behind the scenes power smartphone apps with a modern-looking user interface. This doesn't apply solely to websites, either. If you're having trouble with your application, you can disregard most client-side code, including HTML, CSS, and JavaScript. Since the 504 Gateway Timeout Error indicates that something has gone wrong within your application's server, we can largely disregard the client side. The further the server is from your device, the more "upstream" it is. The terms "upstream" and "downstream" refer to the relative distance of a server from your device. Thus, a server upstream is located higher in the overall server hierarchy than a downstream server.
In general networking parlance, an upstream server is a server that provides a service to (i.e. Similar to the 502 Bad Gateway Error, a 504 Gateway Timeout Error means that something has gone wrong with a gateway or proxy server further upstream. The Problem is Server-SideĪll HTTP response status codes in the 5xx category are server error responses. Throughout this article, we'll examine the 504 Gateway Timeout Error and look at a few troubleshooting tips and potential fixes. As with most HTTP response codes, it can be challenging to determine the exact cause of a 504 Gateway Timeout Error.

A 504 Gateway Timeout Error is an HTTP response status code indicating that a server currently acting as a gateway or proxy did not receive a timely response from another server further upstream.
