Hello to everyone. I'm Lisha, and I practice as an IT expert. Many WordPress users are taken aback when they discover 502 bad gateway wordPress. A 502 Bad Gateway Error indicates that the webserver to which you've connected is functioning as a proxy for transmitting data from another server, but it has received an invalid response from that other server. It's known as a 502 error since that's the HTTP status code used by the webserver to report this kind of issue.
