Hello team,
we have built the functionality for Azure Event-Hub,
in which we call the HttpTrigger method to retrieve data from Webhooks and send them to Azure Event-Hub using Blob Storage.
while calling the HttpTrigger function in a production environment, we encountered the error message shown below.
"HttpTriggerListener Exception binding parameter'req' occurred while the method was being executed. The client has cut off. An attempt was made to use a network connection that didn't exist. (0x800704CD)".
Additional Call Stack Errors Include:

Thank you for reply me.
Scenario:-
we have created an azure function in which ziflow webhook called Httptrigger function to bind webhook event data and send it to azure event-hub.Tools:-
Language:-C#-Azure function
Version:-Dotnet Core 3.1Nudget Package:-
Azure.Messaging.EventHubs(5.3.0)
Microsoft.Azure.Functions.Extensions (1.1.0)
Microsoft.Azure.WebJobs.Extensions.DurableTask(2.4.1 )
Microsoft.Azure.WebJobs.Extensions.EventHubs(4.1.1)
Microsoft.Azure.WebJobs.Extensions.Storage(3.0.10 )
Microsoft.NET.Sdk.Functions(3.0.11)Azure Plan:-
Plan:-Consumption
Azure Function Version :-2.0Code for Reference:- https://wtools.io/paste-code/bD2h
Issue:-
In our function, Ziflow Webhook keeps calling the HttpTrigger Function in order to send event data to EventHub using Httptrigger Function.
When we call an Azure function in the local environment, it works fine, but when we deploy it to the development or production environments, we encounter problems.We were experiencing an error:-
Exception while executing function: ZiflowEventListener Exception binding parameter 'req' The client has disconnected An operation was attempted on a nonexistent network connection.We attempted the following:-
To fix the problem, we upgraded every nudget package, however it did not work.Please let me know if any additional information is required.
Thank you for your assistance -

2022-07-18T14:22:35.427+00:00 Hi @MayankBargali-MSFT ,
As previously stated, our HttpTrigger function was keep calling by a ZiFlow WebHook event, so it sometimes correctly binds parameters but sometimes throws an error.
i have also validated the request parameter in my logic " https://wtools.io/paste-code/bD2h".
Thank You,
Keval Kiniyara. -

2022-07-18T14:32:32.993+00:00 @Keval_ Kiniyara Can you review the Diagnostic and solve problems blade on your function app to see if there is any insights on the issue.
I do see that you have mentioned The client has disconnected An operation was attempted on a nonexistent network connection. so it may be socket exception to where the function app is creating new connection every time to send the event to the event hub.if (SignatureValidator.IsValid(token, requestBody)) { await using var producerClient = new EventHubProducerClient("EVENTHUB-CONNECTIONSTRING", "EVENTHUBNAME"); using EventDataBatch eventBatch = await producerClient.CreateBatchAsync(); eventBatch.TryAdd(new EventData(Encoding.UTF8.GetBytes(requestBody))); await producerClient.SendAsync(eventBatch); }Can you try to reuse the connection by creating the static client and monitor it to see if you still observe the issue.

2022-07-19T11:52:19.803+00:00 Hi @MayankBargali-MSFT ,
We tried creating a static ProducerClient and deploying it in accordance with your advice, but it didn't work.
Although we investigated the Azure function App's "Diagnostic and solve problems," we were unable to determine the root cause of this exception.
Thank You for your assistance.
See the image in the attachment.

2022-07-21T16:30:44.717+00:00 @Keval_ Kiniyara Thanks for sharing more details. It would need one on one support to verify the logs both from the client and server end. I will suggest to create a support request with us to assist you further. In case if you don't have the support plan then please let me know so I can enable one time support request on your subcription.
