I'm running nestJS server (gateway server) and configured http-proxy-middleware
The http-proxy-middleware handle all request to external server (mock server).
If I call from postman to gateway server, the call is proxied to mock server and return response.
But when I call from IOS emulator to gateway server, the call is hang for long time, and I get error:
socket hang up
at connResetException (node:internal/errors:691:14)
at Socket.socketOnEnd (node:_http_client:471:23)
at Socket.emit (node:events:402:35)
at endReadableNT (node:internal/streams/readable:1343:12)
at processTicksAndRejections (node:internal/process/task_queues:83:21) {
code: 'ECONNRESET'
I can see in the gateway server that the URL to mock server is correct, but do not get response.
Also to note that I have company proxy, so I configured the gateway to use agent.
Any advice?

Having a grpc client and server and they are exchanging messages in grpc unary mode. I want to log all the messages the client sends to the server without changing a single line of code in both client or server. I came across to Nginx with its new graceful grpc support. Is it possible to route grpc messages from client to server via Nginx while sending a copy of them to a remote logging service? If No, please let me know if there are any other tools out there that do the same stuff.
My requirement is if a browser sends the request to ServerBootStrap then the ServerBootStrap creates BootStrap (Client) and that client connects with a proxy server.
The problem here is to connect with Proxy Server we need to send first HTTP CONNECT method to open a tunnel from Proxy and BootStrap (Client) and then whatever request comes from Browser to Server, the server will send BootStrap(client) and all the communication should happen.
This will look like
Browser ->ServerBootStrap(Server)->BootStrap(Client)->ProxyServer(HTTP2)
Can somebody tell me how do I implement this for Http2?
How do I send Http CONNECT from a Handler for the First time while Client instantiating and If CONNECT gets 200OK from Proxy Server I will to remove Handler from channel pipeline?
Can we explicitly call any HTTP CONNECT request while adding a handler in Pipeline and getting the response to check the status?
--Can somebody answer ?
I am using a SignalR Client connection using HubConnection. When calling Start(), an System.Net.WebException is thrown with the following message:
The remote server returned an error: (400) Bad Request.
The server response is:
Not a valid web socket request.
I am running Windows Server 2012 R2 with IIS 8.5
What could be the problem?
The problem was with the configuration of IIS.
You have to install the WebSocket Protocol support in order to connect to SignalR using WebSockets.
The problem is this:
I decided to make a messenger/chat (VCL application) with callback on DataSnap technology (IDE Delphi XE6), has created a simple DataSnap server (tcp / ip + http) without the database, and thick client.
All works fine if the whole thing run on a local network (tcp / ip) or via the Internet (http).Problems arise when run over HTTP and the client machine has a HTTP proxy server, the client application can not connect to my DataSnap server application. Client application gets error "10061 connection refused"
or "Expected datasnap context in request http://[YourServerIP]:[YourPort]/datasnap/tunnel".
I tried to enter IP and port of the proxy server to params of component TSQLConnection.Driver params DSProxyHost and DSProxyPort, turned off my firewall and antivirus software, checked allows traffic to the proxy ip + port, but the problem has not disappeared.
After few days searches, without results, i decided listening requests from client application and response of my DataSnap Server application in HTTPTrace procedure of DSHTTPService1 component, also with software HTTPDebugerPro, and i noticed interesting thing:
when client app connecting to ds server app without proxy server, in request ds server app receive URI with this text "/datasnap/tunnel" and all works fine ds server response "200, OK".
when client app connecting to ds server app with proxy, in request ds server app receive URI with text "http://[YourServerIP]:[YourPort]/datasnap/tunnel" and raised exception with response error "404, Expected datasnap context in request http://YourServerIP:YourPort/datasnap/tunnel".
Has anyone knows solution about this problem? How to connect DataSnap client to DataSnap server via proxy server? I searched solution for this problem several days, I shoveled the Internet but have not yet found a solution.
