Hello All,
We have a custom activity (C# .Net code) which loads the data from application and create a CSV file which gets placed over the blob location. This Activity is triggered in ADF with the help of batch services.
This code code is working everywhere except in azure batch.
we have tried running the code on vs, via adf everywhere it is working but in batch getting this error
System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Can you please let us know what would be the cause?
Hi Siddhesh Chavan, Just checking if below answer helps. If yes, please consider hitting Accept Answer button. Accepted answers help community as well. Please let me know if any further queries. Thank you.
As a workaround, you may need to set out the Timeout and ReadWriteTimeout of the request to higher values, or set KeepAlive to false.
Big files uploading (WebException: The connection was closed unexpectedly)

I tried with the code which is provided in link, but still having same error.
While I execute the same code from My local without any change. it generates file and uploads on the desired location as well.
This error I receive when we try to execute the same code in ADF from Batch services over there I gets System.Net.WebException
Hi Siddhesh Chavan,
The error message you provided indicates that there was an issue with the SSL/TLS connection between the client and the server. Specifically, the error message states that "The underlying connection was closed: An unexpected error occurred on a send" and "Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host."
This error can occur for a number of reasons, but one common cause is that the SSL/TLS certificate presented by the server is not trusted by the client. This can happen if the certificate is self-signed or if it is signed by a certificate authority that is not trusted by the client.
To troubleshoot this issue, you can try the following steps:
Check the SSL/TLS certificate presented by the server to ensure that it is valid and trusted by the client. You can do this by opening the URL in a web browser and checking the certificate details.
If the certificate is valid and trusted, try disabling SSL/TLS verification in your code to see if that resolves the issue. This is not recommended for production environments, but it can help you identify the root cause of the issue.
If disabling SSL/TLS verification does not resolve the issue, try capturing a network trace of the communication between the client and the server to see if there are any errors or anomalies in the traffic.
If none of these steps resolve the issue, you may need to reach out to the support team for the service you are trying to access for further assistance.
I hope this helps! Let me know if you have any further questions.
Hello All,
post raising the ticket with Microsoft, they informed it that while our code was executing the memory of VM was going till 100% due to which there was nothing to get store.
post their suggestion to create a new batch pool we were able to establish the connection.
and we were able to execute the activity.
Also, we were using sku '2012-r2-datacenter' whch was metioned by the Support team that is in verge of expiration, so we have created with '2022-datacenter'.
