Yes, Proxy should send a error response upstream. It should not silently
discard the message.
For example see from 3261:
*The server is temporarily unable to process the request due to a temporary
overloading or maintenance of the server. The server MAY indicate when the
client should retry the request in a Retry-After header field. If no
Retry-After is given, the client MUST act as if it had received a 500
(Server Internal Error) response.*
