Paramiko - Incompatible SSH server (no acceptable macs)

I have been using paramiko for a while and everything works as expected, but when I left my test environment, I got this error when opening an ssh session

paramiko.ssh_exception.SSHException: Incompatible ssh server (no acceptable macs)

After tracking the error, I noticed that on my remote server I do not have some entries in my file /etc/ssh/sshd_config. None of my settings are listed in these MAC addresses:

  • HMAC-SHA1
  • HMAC-MD5
  • HMAC-SHA1-96
  • HMAC-MD5-96

However, it works in both one and the other. What could be the reason for this? I do not have rsa keys stored in one (the remote server does not allow writing).

Remote server sshd_config

#
# Allow Ciphers and MACs

Ciphers aes256-ctr,aes192-ctr,aes128-ctr,arcfour256,arcfour128
MACs umac-64@openssh.com,hmac-ripemd160,hmac-sha2-512,hmac-sha2-256

RemoteAccess.py

class RemoteAccess():
    def __init__(self, host="abc123", username="abc", password="123"):
        self.name = host
        self.client = paramiko.SSHClient()
        self.client.load_system_host_keys()
        self.client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        self.client.connect(host, username=username, password=password)
