Wininet Error Codes

This occurs when the camera server is
temporarily unable to process requests due to
server overload (excessive requests from
multiple clients), an uncompleted start-up
process on the camera server, or other
reasons.
This is recorded when the proxy server
returned an HTTP 503 error (which occurs
when the proxy server failed to connect to the
camera server).
504 Gateway Time-out
This is recorded when the proxy server
returned an HTTP 504 error (which occurs
when the proxy server could not receive a
reply from the upper proxy).
