unable to connect to remote device in python

I am trying to connect to my local NAS using SMBConnection

Below is the complete code

from smb.SMBConnection import SMBConnection

def connector():

    conn  =SMBConnection('admin','********',remote_name='MyCloudEX2Ultra',my_name='DESKTOP-I7')
    ret =conn.connect('192.168.0.102')
    print("return val " + str(ret))
    res = conn.listPath(service_name= 'smbclient' ,path= '/Public2')

    for i in res:
        print (i)
    return


if __name__ == "__main__":
    print("In main module")
    ret = connector()

I see that the access didn't go through , on further checking I see on wireshark an error code STATUS_BAD_NETWORK_NAME. I didn't see any reference for this issue , has any one seen similar error and figured out a way to get the access through , below is wireshark output

Edit 1 After removing Try catch block, i see the below error
