I am new using cloud platform. I trying to deploy a service using go and grpc. I found this tutorial https://github.com/GoogleCloudPlatform/golang-samples/tree/master/endpoints/getting-started-grpc and everything was complete successful until I have to call the service.
In the moment that I use the client to call the service I get this error:
could not greet: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: Error while dialing dial tcp 35.199.74.154:80: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because
connected host has failed to respond.
I would like to know if someone can help me with that problem.

I'm figuring out how I can test my golang project using Bloomrpc. I've turned on the backend server, client server and db server but an error pop up like this on Bloomrpc:
I am trying to deploy my laravel project with websockets built on Beyond Code's package.
My server is on AWS and i'm using WHM.
on the cPanel's terminal i'm running the line php artisan websockets:serve
and i get the result Starting the WebSocket server on port 6001...
when i'm loading the page with the websocket's connection sometimes i get the error failed: Error during WebSocket handshake: Unexpected response code: 200
and sometimes i get the error failed: WebSocket is closed before the connection is established.
On AWS EC2's Security Groups i allowed the Custom TCP port 6001 and 6002
Any suggestions to fix it?
Maybe a good deployment tutorial for Laravel WebSockets?
I'm looking for answers all over the internet and i get nothing useful.
I am learning rpc&grpc and go now, i was confused by the grpc.
When I was learning the examples on GitHub（https://github.com/grpc/grpc-go/tree/master/examples）, I encountered some problems. In server, i use address = "ip:50051" instead of address = ":50051"(ip is my intranet ip), and in client i use address = "ip:50051" instead of address= "localhost:50051", then run the server and the client, in client i get the error:
rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: Error while dialing failed to do connect handshake, response: \"HTTP/1.0 504 Gateway Time-out\\r\\nConnection: close
But when i learn rpc in golang, use my intranet ip in the server and client, it is ok.
So i want to know why it is wrong in the grpc?
It seems the client failed to on proxy (failed to do a HTTP Connect handshake).
If you have proxy enabled in your system (the proxy environment variable, HTTP_PROXY or HTTPS_PROXY, is set), make sure the proxy works.
If you don't need proxy, clear the env variables and try again.
I was trying to connect to a server in Go by using gorilla/websocket
and I kept getting the error "unexpected EOF". It took me way too long to find out it was because I needed to use the secure WebSocket protocol to connect to that server ("wss://" instead of "ws://" in my url).
How can I verify that I'm using the wrong protocol for a given endpoint so that I can log a helpful error message instead of "unexpected EOF"?
Unable to connect to the feedback.sandbox.push.apple.com with port number 2196.
Opened the ports (5223, 2915, 2916, 443) in windows firewall with TCP/SSL.
Tried connecting via telnet too, but did not help.
Getting the below exception

Also, this does not need certificate to connect to sandbox, so why this exception?
You do need a development certificate from the Apple Developer portal to connect to sandbox. But I don't know if you need to use it to connect to feedback.sandbox.apple.
I can't seem to find a straight answer on this whether feedback services still works. I think APNS Feedback services are now deprecated. This could be why you're getting this error.
Does APNS Feedback service no longer exist as per new APIs?
APNS Feedback Service - is it still alive?
