hello, I have such a situation in the document definition, I recognize 10 documents and for each document a script is registered that writes the data to a text document and sends it to the FTP server, respectively, each script opens a session on the server when it starts, where the maximum number is 8 open.After recording, you will see that I am sending through WebClient, as I read that it closes the session behind itself, and if it didn’t close then client.Dispose(); helps it close but still i get the same error after export to server 421.I ask for your help how to do it right or fix this script.

Regards Vladimer
