"connection closed" - Miniserver connection error: Socket Error: read ECONNRESET (1006)

[DSew20]

Hello - has anybody noticed that the MiniServer connection keeps dropping in / out?

I seem to be getting connection issues every few minutes. The error message shown under each node is "connection closed". I also get the following error in the debug console:

"Miniserver connection error: Socket Error: read ECONNRESET (1006)"

This code has been so stable for as long as I can remember. But, it seems to be having issues at the moment. I'm on the latest version of node-red-contrib-loxone (v10.12), v2.05 of Node Red and the latest MiniServer version (v13.06.29).

Any thoughts on how to isolate / fix the problem?

[DSew20]

Hello - does anybody have any ideas as to why the connection keeps closing? To add to above, I have updated Note-Red to v2.2.2. The issue remains.

This had all been working great for months. But, for some reason, the connection keeps dropping. It connects, works ok, then connection closes / drops. Any ideas how to troubleshoot / fix?

Hey @DSew20,

we will have a look into this but we currently have time constraints. @codmdu could you maybe give this a look?

[gahujipo]

I think this issue describes the same problem as in #73

[centauri]

Got the same error. Node red is constantly rebooting

[UtechtDustin]

I'm not able to reproduce it right now, can somebody please add the following line console.log(">>>", this._ws.connection.closeDescription) to the file USER-DIR/.node-red/node_modules/node-red-contrib-loxone/node_modules/node-lox-ws-api/lib/Connection.js between line 146 and line 147. (Right after Connection.prototype.send = function (message) {).

After that restart node-red and copy & paste the log to this issue. Thanks in advance.

[3HMonkey]

Hey I checked this, it is "null".

[UtechtDustin]

@3HMonkey Thank you, is it always null ? The first 3-4 lines should be null, but is it also null when the error occurs ?

[3HMonkey]

Let me setup a plain process.

This is the clean start without a flow which is working great.

Starting as a systemd service.

Then I went setting up a new connection for the miniserver which is also working receiving the structure:

After deploying nodered is restarting over and over. Yes, first it is null, then forbidden since it is reaching the reconnect counts:

@3HMonkey You're credentials or the ip of the miniserver are wrong

>>>>>>>> Forbidden - IP 192.168.178.34 temporarily blocked, too many failed login attempts (1)

[3HMonkey]

I do not think so since the credentials are stored inside the connection. Also with the wrong credentials it is impossible to parse the structure of the miniserver. Maybe the method changed due to an update of loxone?

[UtechtDustin]

You're right, so we have to figure out why the miniserver returns this message.

Which method to you mean ? We currently run version 13.1.10.19, with correct credentials it works fine for us.

[3HMonkey]

I also thought about that, so I decided updating it today also.

Ill stop the nodered server and wait for the timeout and start it again and provide the logs. Is there a command I can store the logs of node-red into a file?

[3HMonkey]

[3HMonkey]

Here is the full log until it swap to "forbidden"
