System.Net.Sockets.SocketException (10060)

[tthirmal]

I am getting System.Net.Sockets.SocketException (10060), while downloading the files from SFTP into Azure Blob storage using C#, and this code is working fine in my local machine(running manually in Visual Studio 2019), but the problem is after published my code into WebJobs it's getting failed and giving attached Errors.
