Socket disconnect after a while

[Sapessii]

Hi!

I am facing an issue both in local (Mac OS Sonoma 14.2) and deployed on render.com.

Basically after a while the socket close without receiving further updates and I get this error:

2024-01-26 04:04:08,363:ERROR - Connection with the server closed.
Traceback (most recent call last):

The above exception was the direct cause of the following exception:

raise self.connection_closed_exc()
websockets.exceptions.ConnectionClosedError: no close frame received or sent

To Reproduce

1. Launch the server with python main.py
2. Wait a while without receiving updates on the socket

Expected behavior

The socket should't disconnect.

Additional context

This is my current python code

if __name__ == "__main__":
    URL = f"wss://{os.getenv('SUPABASE_ID')}.supabase.co/realtime/v1/websocket?apikey={os.getenv('SUPABASE_SERVICE_KEY')}&vsn=1.0.0"
    s = Socket(URL)
    s.connect()

    channel_1 = s.set_channel("realtime:public:todos")
    channel_1.join().on("INSERT", lambda msg: asyncio.ensure_future(callback(msg)))

    s.listen()

Having the same issue -- any updates or workarounds on this?

Same issue with me.

I think it comes down to:

• There will always be a disconnect when working with websockets
• You should auto_reconnect (client option).
• The auto_reconnect should rejoin channels

However, the auto_reconnect does not seem work properly for me and ignores new events after reconnect. I fixed that behavior in an opinionated fork. This fork does have breaking changes
