I am trying to send a file from the master node to minion nodes using a python script but a single error OSError: Failure keeps on coming up.

I tried to code this file to send this file from one local machine to another local machine.

My code:

    #! /usr/bin/python
    #! /usr/bin/python3
    
    import  paramiko
    import os
    
    #Defining working connect
    def workon(host):
        #Making a connection
        ssh_client = paramiko.SSHClient()
        ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())  #To add the missing host key and auto add policy
        ssh_client.connect(hostname = host, username = 'username', password = 'password')
        
        ftp_client = ssh_client.open_sftp()
        ftp_client.put("/home/TrialFolder/HelloPython", "/home/")
        ftp_client.close()
    
        #stdin, stdout, stderr = ssh_client.exec_command("ls")
        #lines = stdout.readlines()
        #print(lines)
    
    def main():
        hosts = ['192.16.15.32', '192.16.15.33', '192.16.15.34']
        threads = []
        for h in hosts:
            workon(h)
    		
    main()

		

Error:
