I am unable to reproduce this issue as describe. I tried your examples and recreated a unit test.

import rpyc
from rpyc.utils.server import OneShotServer
import unittest


class MyService(rpyc.Service):

    def exposed_concat(self, remote_str):
        local_str = ' github'
        return remote_str + local_str

class Test_OneShotServer(unittest.TestCase):

    def setUp(self):
        self.server = OneShotServer(MyService, port=18878, auto_register=False)
        self.thd = self.server._start_in_thread()

    def tearDown(self):
        self.server.close()
        self.thd.join()

    def test_server_stops(self):
        conn = rpyc.connect("localhost", port=18878)
        self.assertEqual("hello github", conn.root.concat('hello'))
        conn.close()


if __name__ == "__main__":
    unittest.main()

The output to the above unit test:

My best guess without being given your output is a connectivity issue: something may be preventing the connection (macOs permissions, Windows AV, etc.) or the server was not running (OneShot will serve a single request before shutting down).

Feel free to reopen with more details such as logs/errors, rpyc version, and operating system.
