[Python] Randomly getting "Error reading SSH protocol banner" in Paramiko

I am trying to transfer CSV file from one server to another using Paramiko, SSH connection.

I never had any issues with all transfers, but for some random files, I have that:

SSHException: Error reading SSH protocol banner
​

This is strange because it happens randomly on any file, given that size of the file is almost same. Is there any way to fix it?

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(**self.config, timeout=10, banner_timeout=60)`


after that,

sftp = ssh.open_sftp()
sftp.put(local_path, remote_path)
sftp.close()
ssh.close()
