What is a Prestashop 502 bad gateway error ?

Status code 502 (Bad Gateway) indicates that the server, acting as a proxy or gateway, received an unsatisfactory response from the server it accessed to fulfill the request. Every time you visit a website, your browser sends a message to the web server. The web server processes the request and then returns the requested resource with an HTTP header and an HTTP status code. Generally, the HTTP status code is not visible unless there is a problem. It's basically how the servers alert you that something is wrong, and also provide you with instructions on how to fix it. Are you interested in launching an e-commerce site?
