Grpc-web: Use 'grpc-web-client ' can't connect for more than 10 seconds.

[AaronJin2013]

When I connect the grpc server，it's can keep long connect，and use debug，it's return

MozXHR.onStateChange 3
MozXHR.XMLHttpRequest.HEADERS_RECEIVED 2
MozXHR.onProgressEvent:  
Uint8Array [ 0, 0, 0, 0, 0 ]
rawOnMessage 
Object { value: false }

But when it's 10 seconds，it's return

MozXHR.onStateChange 4
MozXHR.XMLHttpRequest.HEADERS_RECEIVED 2
MozXHR.onLoadEvent
grpc.onEnd
grpc.headers only response  null 
Array []
rawOnEnd 13 Response closed without grpc-status (Headers only) 
Object { headersMap: {…} }
GRPCrequest.onEnd 13 Response closed without grpc-status (Headers only) 
Object { headersMap: {…} }

I want to maintain a long-term connection. Is there any way?

It's the grpcwebproxy timeout setting，need set it on server

@AaronJin2013 Thank you for posting the solution, I ran into this issue as well. More specifically, you can set the --server_http_max_write_timeout command-line flag to a value that time.ParseDuration can read. I set it to 1h in my case.
