Error when connecting SMBConnection to remote servers, please help me understand what is the error?

Question

Python

I made an application for synchronizing revoked servificato between servers, when it comes to copying, the application crashes with an error, maybe I don’t understand the workflow in my case, maybe someone can point me in the right direction?)
Error:

Traceback (most recent call last):
  File "c:\users\november.31st\documents\visual studio 2017\Projects\CopyCRL\CopyCRL\CopyCRL.py", line 28, in <module>
    copysrvmain = shutil.copytree(srcsrv+srcsrvpath, srv+dstpath)
  File "C:\Users\November.31st\AppData\Local\Programs\Python\Python35-32\lib\shutil.py", line 303, in copytree
    names = os.listdir(src)
FileNotFoundError: [WinError 3] The system cannot find the path specified: '127.0.0.1\\CRL'

client_machine_name = 'QUIK_SYNC'

config = configparser.ConfigParser()
config.read('copycrl.ini')

conndst = SMBConnection(usr, usrpwd, client_machine_name, srv, use_ntlm_v2=True, is_direct_tcp=True)

connsrc.connect(srcsrv, 445) #Открываем конекты.
conndst.connect(srv, 445)

Simple init:

[user]
user = Broker
pwd = 111

[usersource]
user = Broker
pwd = 222

[source]
srv = 127.0.0.1
path = \CRL

[dst]
path = \CRL

[servers]
dstsrv = 192.168.150.120
