General

Hi all.

I've a problem with MQTT in node I use mosquitto.
When i make full deploy (ex. move MQTT in node) I get this error back on the debug console,
"Error stopping node: Close timed out"

mosquitto version 2.0.11
mosquitto is an MQTT v5.0/v3.1.1/v3.1 broker.

I got the same issue so I disabled all my mqtt nodes, deployed and re-enabled them. It deploys without the error now.
Maybe this will work for you too?

Whoops, spoke too soon. It's back again!

after you reenable have you then tried to move a mqtt node and deploy it? I still have the same error now also on the mqtt output node

Don't install any mqtt broker (ex. MOSQUITTO on my case) install only node red..

Not installing an Mqtt broker ? what if you need it ? :wink:
an update of Node-red to 2.2.2 was released a couple of days ago
addressing the "Error stopping node: Close timed out" issue.
