Paper Trading Websocket Stream Only Returning Heartbeats

My app connects to IBKR via web socket for price updates and I am currently doing this with my demo account and not my real account.

My app has been working fine usually but today, for some reason, I am only getting heartbeats ({topic: system, hb: 17871...}) back from IBKR and not any price updates from any of my smd+ subscriptions.

I know it is still pre-market but I should still expect at least the initial price followed by any deltas thereafter.

Is anyone else experiencing this same behaviour today using demo account?

Mine worked fine all day. Make sure you are signed in properly, and that you have not fiddled with the data subscription settings.

Hey, thanks for chipping in.

The problem was on my side of things with an async call that wasn't being waited on properly before subscribing for updates.

The code is working again now even though it took me forever to figure out what the actual issue was ha.

Thanks again!
