Internal Server Error
A generic error message, given when an unexpected condition was encountered and no more specific message is suitable.
Bad Gateway
The server, while acting as a gateway or proxy, received an invalid response from the inbound server.
Service Unavailable
The server cannot handle the request because it is overloaded or down for maintenance.
