I noticed a pattern of my Chat App sending a 'socket hang up' error message every couple of days.
pic of UptimeKuma logs I figured out that this is an exception being thrown by the server, and found this article outlining possible reasons for a socket hang up error when using websockets in node.js and express.js.

Right off the bat, I noticed that my server's source code - which I wrote back in the Spring of last year - is using http. This works fine for running the app locally in port 3000 during development. However, the production app is receiving requests for a https connection. *but then why wouldn't I see this exception all the time in the logs?

Wait a minute, could it be that the hang up is happening on the front - end side somehow? I ask this because uptimekuma is simply grabbing the response being sent to the web browser over the network.

wait a minute, perhaps this is the 'expected heartbeat'. But if that is the case, then why is it taking hours to show 200 OK again after the 'web socket hangup' in the wee hours?

I decided to see if I could monitor the websocket activity in wireshark.Also , I am going to try to manually re-create this the next time I see a 'down' message showing 'socket hang up' from uptimekuma.

10/9/23: I woke up to a 'socket hang up' down message in uptime kuma. I went to where I had the app open in chrome and refreshed the browser. it worked fine. uptimeKuma notifed 'app back up'. ?
