do not user underscore methods if you dont know what you are doing ( internal methods ) use "server.set_endpoint(" like in the examples 😉

Examples: https://github.com/FreeOpcUa/python-opcua/tree/master/examples

Undescore: https://www.datacamp.com/community/tutorials/role-underscore-python#SLU Single Pre Underscore is used for internal use. Most of us don't use it because of that reason.
