I am trying to connect to gateway.sandbox.push.apple.com through "apns-sharp" class library, but all I get is the following error message: "A connection attempt failed because the connected party did not properly
respond after a period of time, or established connection failed because connect
ed host has failed to respond 17.172.238.209:2195"
Why Is That?
Your provider may not allow to go out using port 2195.

I am using System.Net.WebSockets to create a websocket client to a websocket server I am running. The following code is used to create the websocket
Debug.Log("Setting up websocket");
client = new ClientWebSocket();
await client.ConnectAsync(new Uri("ws://192.168.68.93:8001/ws"), System.Threading.CancellationToken.None);
Debug.Log($"Socket status: {client.State}");
The following error is produced:
System.Net.WebSockets.WebSocketException (0x80004005): Unable to connect to the remote server ---> System.Net.Sockets.SocketException (0x80004005): 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.
The confusing part to me, the following code in javascript works perfectly fine
const ws = new WebSocket("ws://192.168.68.93:8001/ws")
And if I log the messages I receive, they are what I expect/work perfectly fine.
What would cause a JS websocket to work, but not a C# one?
My current suspicion is the issue is actually related to the wsserver, I am running it on an esp32, using a library called ESPAsyncWebServer. But I need to know why C# would fail on it when JS works fine
I am getting the following exception in cluster.Connect while performing load testing in my application.
All hosts tried for query failed (tried :: SocketException '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'; :: SocketException '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'; ...)
The exception is thrown only when I overwhelm my application with a large number of requests (1000 or more). However, it seems to work fine for small number of requests because of which I am eliminating the possibility of a firewall issue. For some reason, this call gets stuck which leads to a deadlock in my application. Any help is greatly appreciated. Thanking in advance.

I have a TCP server which has a receive timeout of 9 seconds, however, I am using to receive any data from the client:
while (sr.Peek() >= 0) {
line += sr.ReadLine();
line += Environment.NewLine;
}
But when the server times out I get the following error on the sr.Peek() line:
System.IO.IOException: Unable to read data from the transport connection: 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. ---> System.Net.Sockets.SocketException: 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
Is there a way of having a timeout but also waiting for any potential data from the client?
I have a server object as
TcpChannel tcp = new TcpChannel(1234);
ChannelServices.RegisterChannel(tcp, false);
string s = ConfigurationManager.AppSettings["remote"];
RemotingConfiguration.RegisterWellKnownServiceType(typeof(TestRemoting.InitialClass1), "TestRemoting", WellKnownObjectMode.Singleton);
Console.WriteLine("Server is running on 1234 channel...");
Console.WriteLine("Press Enter to Stop");
Console.ReadLine();
and I am accessing that object in mu client form like
InitialClass1 Icls = (InitialClass1)Activator.GetObject(typeof(InitialClass1), "tcp://localhost:1234//TestRemoting");
Now I am keeping my remote object in another computer. How can I access my server object from that computer. If I access the server object from my (local) computer, I will use
"tcp://localhost:1234//TestRemoting"
I am using localhost here, because my server object and my client is same. So If those two are different, How can I access the server object.
I tried with my another computer IP
as
tcp://200.100.0.52:1234//TestRemoting
that time I am getting an exception as
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 200.100.0.52:1234
The message means most of the time that the client cannot find the service. You can use the following steps to determine where the connection fails:
Check if the service is running on the remote machine.
Check if the port number is correct.
Ping the remote machine from the client.
Open a telnet session to the remote machine on the port number of service.
The step on which it fails gives an indication of why it is failing.
I wrote a simple tcp/ip chat and it worked with the localhost IP(127.0.0.1) as well as connecting to another computer on the local network.
Through the Internet (v4 IP address) it didn't work so I tried the codeproject example:
I downloaded but it threw the same exception on connecting:
TcpClient Client = New TcpClient(IPAddr, 65535);
I tried with another port and turned off Windows-Firewall and Avira-Free.
Update:
If I connect to another Internet IP address, the following exception is thrown:
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 IP-Address: 65535
Probably this won't help, but perhaps try another port?
