Close received after close

[vCloudSail]

Why is this error always reported when running for a long time: WebSocket connection to 'ws://xxx/mqtt' failed: Close received after close

version: 4.2.8
browser: Microsoft Edge 95.0.1020.53

Great question. I dunno. Close received after a close suggests that the websocket connection was closed and then subsequently there was a call to close that same websocket connection despite it already being closed. Can you repro it repeatably?

I encountered the same problem, I need to close the socket when reconnecting, but how to configure the code?

I can't manually reproduce this situation, which typically occurs multiple times after MQTTJS has been running for a long time

I have changed to the paho.mqtt.js library

It's happen when you leave tab inactive for duration more than ~ 1 minutes

Do you mean web sleep is the cause?

[amnonbb]

Sorry, din not understand.
Actually yes, looks like it's cause by web sleep.

@amnonbb can you provide a reproducible code snippet please. will attempt repro and debug.

I discovered that if i connect with keepalive option = 1 or 2 sec, the error above fire after ~ 5 seconds on inactive tab

[YoDaMa]

@amnonbb and you're just starting a client, connecting via WS, and sending messages? do you have a code snippet i can paste and run?
