Step 1:- We are connecting to a website using our web browser [Chrome, IE, Mozilla, Opera etc.]
Step 2:- Then we are providing our browser a URL address eg: https://firstandgeek.com/document.html

Here the URL have 3 parts, the HTTP part, the host name part www.firstandgeek.com and finally the file path document.html. The first path called HTTP is a standard protocol need to be followed when some web browsers and web servers interacts each other.

The second part known as the host name or the domain name which is actually a conversion of an IP address which identifies your server computer where the website files actually stored. We are converting the IP address to domain name to make it more readable. For example the IP address of firstandgeek.com is 103.21.59.20 and if every website is like this, how many of them can be remembered?

Step 3:- So while giving a URL to your browser, it get converted to corresponding IP and locates the computer server where the files actually exists and bring them back to the client computer within the browser.

The reason behind the 504 gateway timeout errors in a website

The person behind each and every website may different so the way in which they customize the error 504 may also change. It is the webmaster who can decide how a website should look like once an error 504 encountered. So you may have seen different kind of 504 errors.

  • gateway timeout error 504

Anyway these errors are same. All these messages get listed on a browser window once such situation get encountered.
The probable reason for this 504 error is the issue with the servers. The servers are now not capable for serving the client request. For some website, there my have multiple servers in different location. Multiple servers are using for serving the contents to the client in a quick manner and for load balancing. If one server need to access the other one for resources, there may have time delay and made impact on the front end if the request at a time is very high.
Some company’s may have hosted their website with cheap servers which are not compatible with handling many requests at a time. For example, in India, most of the university websites get “504 gateway timeout” at the time of result declaration and at the time of allotments. This is because of the cheap servers with which the website are hosted.
If you are planning to purchase any servers for hosting, most of the company’s offer 99% up time. Just convert this % to time. That means in 100 minutes, your server will not available for 1 minute. In a day, there are 24*60=1440 minutes. Then your servers can be down for approximately 14 minutes. This all makes the 504 error.
