I added the option --backend_tls=true, and now my grpc server is throwing:
ssl_transport_security.c:947] Handshake failed with fatal error SSL_ERROR_SSL: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number.
chttp2_server.c:123] Handshaking failed: {"created":"@1491644898.916048787","description":"Handshake failed","file":"../src/core/lib/security/transport/security_handshaker.c","file_line":274,"tsi_code":10,"tsi_error":"TSI_PROTOCOL_FAILURE"}
and grpcwebproxy throws:
INFO[0013] transport: http2Client.notifyError got notified that the client transport was broken EOF. system=system
EDIT: my node grpc server is using [email protected]
EDIT2: using the --backend_tls_noverify=true can be a workaround

I think I mixed these two flags:
--server_tls_client_ca_files--backend_tls_ca_files
What I need for my grpcwebproxy to connect to backend grpc server that is using self-signed cert is the second flag I guess?
Still, starting grpcwebproxy with the "correct" flag still complain with:
Failed to dial localhost:50052: connection error: desc = "transport: x509: certificate signed by unknown authority"; please retry. system=system
and here is my grpc server error:
ssl_transport_security.c:947] Handshake failed with fatal error SSL_ERROR_SSL: error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate.
chttp2_server.c:123] Handshaking failed: {"created":"@1491648095.618424166","description":"Handshake failed","file":"../src/core/lib/security/transport/security_handshaker.c","file_line":274,"tsi_code":10,"tsi_error":"TSI_PROTOCOL_FAILURE"}
I'm using --backend_tls_noverify=true for now.

Closing this issue as it's a question (and it would appear no-one has the answer) - may I suggest you post on stackoverflow using the grpc-web tag?
Thanks :)
