Hi, i add a new node, but not connect with CeSi:

Traceback (most recent call last): File "/opt/cesi/cesi/core/handlers.py", line 9, in wrapped return f(*args, **kwargs) File "/opt/cesi/cesi/core/node.py", line 43, in get_system_list_methods_for_xmlrpc_server self.connection.system.listMethods() File "/usr/lib64/python3.7/xmlrpc/client.py", line 1112, in call return self.send(self.name, args) File "/usr/lib64/python3.7/xmlrpc/client.py", line 1452, in request verbose=self.verbose File "/usr/lib64/python3.7/xmlrpc/client.py", line 1154, in request return self.single_request(host, handler, request_body, verbose) File "/usr/lib64/python3.7/xmlrpc/client.py", line 1187, in single_request dict(resp.getheaders()) xmlrpc.client.ProtocolError: <ProtocolError for 10.54.130.34:80/RPC2: 404 NOT FOUND>

During handling of the above exception, another exception occurred:

on port 80 is running an nginx proxy to supervisor port.

Which ports should I open? Regards,
