Hey, don't know if someone have got this, but as I'm using the .ftp.FTPSClient I'm getting a random set of errors Remote host terminated the handshake and Socket is closed for a different combination of user/password/directory in the same server, with multiple instances in multiple threads connecting to the server concurrently, but it's not heavy concurrent, I'm just spinning 20 threads, one for each combination. I'd like to know if anyone have seen this sort of error before. I'm using a retrying approach but I'm still getting failures.
