want to ask : cannot jump to router with debug error : DEBUG:paramiko.transport:Rejecting "hostkeys-00@openssh.com" global request from server.

Hi all,

I want to ssh to router via jumphost.

1. ssh from windows ssh terminal to jumphost (linux machine) : ok
2. SSH from jumphost to router : ok
3. using jumpssh + netmiko: nok. Error message:
   -->
   Traceback (most recent call last):
   File "C:\Program Files\Python311\Lib\site-packages\netmiko\base_connection.py", line 1138, in establish_connection
   self.remote_conn_pre.connect(**ssh_connect_params)
   File "C:\Program Files\Python311\Lib\site-packages\paramiko\client.py", line 386, in connect
   sock.connect(addr)
   TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
   <--

our code is taken from : https://python-forum.io/thread-26866.html
from netmiko import ConnectHandler
from jumpssh import SSHSession

targetnode = {
'device_type': 'alcatel_sros',
'ip': 'targed_node',
'username': 'admin',
'password': 'admin',
'port': 22,
}

jh_session = SSHSession('jumpserver_ip','jumpserver_user',password='jumpserver_passwd').open()
remote_connect = ConnectHandler(**targetnode)
output = remote_connect.send_command("show router interface")
print(output)

we modify ip and username and password.
But it cannot connect.

Enabling debug, we got :
...
INFO:paramiko.transport:Authentication (password) successful!
INFO:jumpssh.session:Successfully connected to 'jumphost:22'
DEBUG:paramiko.transport:Received global request "hostkeys-00@openssh.com"
DEBUG:paramiko.transport:Rejecting "hostkeys-00@openssh.com" global request from server.
DEBUG:paramiko.transport:EOF in transport thread
...

apparently it can connect to jumphost, but then got message : DEBUG:paramiko.transport:Rejecting "hostkeys-00@openssh.com" global request from server.

What should we do ?

thanks.
