Getting socket exception while calling AdobeSign API like get agrreement api

Urgent

We are using the Adobe Sign API to retrieve and store signatures within a Nintex workflow. Adobe provides two relevant actions: Get Signature and Store Signature. In our implementation, we have integrated Azure Functions within our connector service to interact with various Adobe Sign API endpoints, including agreement retrieval and more.

One of our customers is experiencing intermittent issues while executing the Get Signature method. This method triggers an HttpClient call from within our .NET Azure Function. While the request occasionally completes successfully, it often fails with one of the following exceptions:

1. System.Net.Sockets.SocketException

 

vbnet
CopyEdit
The request was canceled due to the configured HttpClient.Timeout of 100 seconds elapsing. The operation was canceled. Unable to read data from the transport connection: The I/O operation has been aborted because of either a thread exit or an application request.

 

 

2. SSL/TLS Exception

 

vbnet
CopyEdit
The SSL connection could not be established. Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
 

We are only observing this issue with a few specific Adobe Sign accounts — not all.

Can anyone help us understand the possible cause of these intermittent failures?
Is there any kind of restriction or limitation at the Adobe Sign account level that could lead to this behavior?
