مشکل در اتصال به نودها

[sasanam]

در هنگام اتصال به نود ها ارور زیر و میگیرم :

'NoneType' object has no attribute 'peer' ========= Remote Traceback (1) ========= Traceback (most recent call last): File "/usr/local/lib/python3.10/site-packages/rpyc/core/protocol.py", line 356, in _dispatch_request res = self._HANDLERS[handler](self, *args) File "/usr/local/lib/python3.10/site-packages/rpyc/core/protocol.py", line 837, in _handle_call return obj(*args, **dict(kwargs)) File "/code/rpyc_service.py", line 127, in restart config = XRayConfig(config, self.connection.peer) AttributeError: 'NoneType' object has no attribute 'peer'

مشکل کجاست ؟
