Try this instead:

    error_page 497 = @http;

    location @http {
        proxy_pass http://upstream.server;
    }

But, as previously said, it might not be a good idea to actually 
configure things that way.  Rather, 497 can and should be used to 
return a proper error and/or redirection to the correct address 
with the protocol properly specified.
