It prevents the requested data from being loaded, meaning that first, you waste time and, second, you can miss something important. Therefore, having this clear is crucial to having the capacity to overcome this error and know what triggers it. As much as this post focused on the listicle, we’ve also included other paragraphs to make it easier for you to read about ways of dealing with the 504 Gateway Timeout error.
1. Let me explain what does mean 504 Gateway Timeout Error?.
The 504 Gateway Timeout error message appears when a server acting in this capacity has not received a proper response from a next-tier server. This issue is not the client or the user side issue, but the issue is the server and the network support of the website you are trying to see.
2. Preconditions to the Occurrence of the 504 Gateway Timeout Error
- Server Overload: Another cause of 504 error is when a server receives too many requests at once to the extent of overloading the server. This can be caused by excessive traffic, the number of users who access the site at the same time, or attempts at a ‘Denial of Service’ attack.
- Upstream Server Unavailable: This may be due to maintenance, the server freezing or any other problems that would bar the server from accepting requests. In such cases, the gateway server itself cannot get any response from the upstream server.
- Slow-responding Applications or Scripts: If the application or script concerned with implementing the requests processing takes much time to process the request, then a timeout message will be generated by the gateway server.
- Network Issues: At other times, the problem might be located within the network system itself. Unavailable data, architecture issues, disaster situations, software problems, slow or busy routes or even network hardware damages may cause 504 errors.
3. How to Address the 504 Gateway Timeout Error.

- Upstream Server Maintenance: If it is indeed with the upstream server, then one should wait for the connection to be re-established or consult the hosting service provider.
- Fix Slow-responding Scripts or Applications: Make sure that you are getting the most out of your code; look for faster scripts that can replace the old ones.
