OSError: errno 99 cannot assign requested address

I have built an app with Django and I have written a command that processes Excel files, generating json files which are then copied to a remote machine using Paramiko. When I execute the command manually works perfectly, however, when it's ran by the crontab throws the exception

File "/code/blacklist_app/models.py", line 76, in upload
    ssh.connect(host, username=usuario, password=password)
  File "/usr/local/lib/python3.8/site-packages/paramiko/client.py", line 349, in connect
    retry_on_signal(lambda: sock.connect(addr))
  File "/usr/local/lib/python3.8/site-packages/paramiko/util.py", line 283, in retry_on_signal
    return function()
  File "/usr/local/lib/python3.8/site-packages/paramiko/client.py", line 349, in 
    retry_on_signal(lambda: sock.connect(addr))
OSError: [Errno 99] Cannot assign requested address

@jorguerra I'm having the same problem, did you solve it?

@Krystex The errno 99 (EADDRNOTAVAIL) typically occurs when no ephemeral ports. Please check the setting of net.ipv4.ip_local_port_range.
