How do I use my droplet as a server using the python websockets module?

I’m a complete beginner to network programming. I’m writing a program to allow me to play board games with my friends throughout isolation (I know, I know, there are already similar programs available online, but I want to make my own to make myself a better programmer). I’m trying to use the websockets library on python to allow me and my friends to connect to the droplet I’ve set up. When my client tried to connect to the server I get the following error:

RuntimeError                              Traceback (most recent call last)
~\Desktop\test_program\client2.py in <module>

    558         future.add_done_callback(_run_until_complete_cb)
    559         try:
--> 560             self.run_forever()
    561         except:
    562             if new_task and future.done() and not future.cancelled():

    513         self._check_closed()
    514         if self.is_running():
--> 515             raise RuntimeError('This event loop is already running')
    516         if events._get_running_loop() is not None:
    517             raise RuntimeError(

RuntimeError: This event loop is already running

Does anyone know what I might be doing incorrectly? Could it be an issue with the firewall on my computer or on my droplet?

Thanks, Robert
