What is the 502 Bad Gateway Error?
This type of error represents a communication problem between two servers. It occurs when the client computer connects to a server that acts as a gateway or proxy and needs to access a server that is in a higher hierarchy and that provides an additional service, such as a name server ( DNS).
As seen in the image, a connection is made between two servers and for some reason one does not understand the request made by the other, it is at this moment that Error 502 jumps, since the server does not understand the request does not know what to show and gives the Bad Gateway, seeing the following image on your screen.
Why am I getting Error 502 Bad Gateway? Causes Error 502
When the Bad Gateway error appears, it is usually the fault of the higher-level server to which the request is made, and normally it is not the fault of the browser or the client’s part. However, there are always exceptions and on some occasions the problem does not come from the server but from the browser, this being the least common.
When the Bad Gateway error appears, it is because the higher-level server has not responded to the request.
Main causes of Error 502
- Server down or overloaded
- Communication error between the two servers have not agreed on the protocol to be used for the exchange of information
- One of the servers is not properly configured or programmed
- Browser error
- CDN (in case you use one on your website)
In most cases the server does not have to be down, but in the communication between the two servers they have not agreed on the protocol to be used for the exchange of information. This usually happens when one of the servers is not properly configured or scheduled.
