Error 502 Bad Gateway indicates that the HTTP status code server is receiving
an invalid response from another server on the internet. When you visit a
website, the browser itself stores some data from the page in cache memory so
that it loads quickly the next time you visit the same page. When this cache
memory is full, your browser will no longer be able to save data and you will
receive a 502
Bad Gateway error code. This error can be easily fixed by clearing your web
browser cache files. There are many other possible causes, and we will discuss
their solutions later in this article. To review these factors and simple
solutions, read this section to the end or contact our technical support
