How to fix rethinkdb connection refused problem?

I'm following this guide here https://github.com/flaree/Flare-Cogs/tree/master/dankmemer. I got to the import rethinkdb part but I get this error when running the r.connect('localhost', 28015).repl() command. Been searching yesterday for a fix but couldn't find one.

r.connect('localhost', 28015).repl()
Traceback (most recent call last):
  File "/root/venv/lib/python3.8/site-packages/rethinkdb/net.py", line 349, in __init__
    self._socket = socket.create_connection((self.host, self.port), timeout)
  File "/usr/lib/python3.8/socket.py", line 808, in create_connection
    raise err
  File "/usr/lib/python3.8/socket.py", line 796, in create_connection
    sock.connect(sa)
ConnectionRefusedError: [Errno 111] Connection refused

During handling of the above exception, another exception occurred:

  File "<stdin>", line 1, in <module>

Solution

You need to run rethinkdb first. Enter your venv, and run tmux. Then run rethinkdb inside your tmux shell. This starts the rethinkdb server, and keeps it running. Close the SSH session, and open another one. Try running your code again.
