Connection to test SFTP server on 0.0.0.0

I am trying to connect and upload / download a text file via Python, but I am getting this error:

Traceback (most recent call last):
File "C:\Users\Abdul\OneDrive\Desktop\SFTP neu\main3.py", line 8, in <module>
c.connect(hostname = "0.0.0.0",port = 22, username = "tester", pkey = k)
File "D:\Python\lib\site-packages\paramiko\client.py", line 349, in connect
retry_on_signal(lambda: sock.connect(addr))
File "D:\Python\lib\site-packages\paramiko\util.py", line 283, in retry_on_signal
return function()
File "D:\Python\lib\site-packages\paramiko\client.py", line 349, in <lambda>
retry_on_signal(lambda: sock.connect(addr))
OSError: [WinError 10049] Die angeforderte Adresse ist in diesem Kontext ungültig

I'm using Rebex TinySFTP Server.

At first I thought my host was wrong, but that wasn't it. In this example I used 0.0.0.0.

enter image description here

Here is my code:

#!/usr/bin/python3
import paramiko

k = paramiko.RSAKey.from_private_key_file("C:\\Users\\Abdul\\OneDrive\\Desktop\\RebexServer\\private-rsa-key.pem")
c = paramiko.SSHClient()
c.set_missing_host_key_policy(paramiko.AutoAddPolicy())
print("connecting")
c.connect(hostname = "0.0.0.0",port = 22, username = "tester", pkey = k)
print("connected")
commands = ["C:\\Users\\Abdul\\OneDrive\\Desktop\\RebexServer\\data\\testfile.txt", "C:\\Users\\Abdul\\OneDrive\\Desktop\\SFTP neu\\data\\testfile1.txt"]
for command in commands:
    print("Executing {0}".format( command ))
    stdin , stdout, stderr = c.exec_command(command)
    print(stdout.read())
    print("Errors")
    print(stderr.read())
c.close()

0.0.0.0 is often used when starting a server to indicate that the server should bind to all available IP addresses. But it's not what you should use in your client.

Use one of the actual IP addresses your server is binding to. If both are on the same machine, try 127.0.0.1 or whatever IP address you are using locally. Addresses starting with 192.168. are common in home and small office networks.
