contrib blynk does not recover if mqtt broker goes down

[Toshibass]

As title, needed to reboot node-red to fix the issue.

One point because I am testing Node.js version: v0.10.36 re: #18 issue, my mqtt broker is not on the same pi as this node-red instance. I stopped the mqtt broker nothing related to contrib-blynk.

hi,
everything in the log says that mqtt is not connecting, can t see anything about blynk.
does it show disconnected in the interface?

[Toshibass]

For sure your right the original problem is that Mqtt disconnects (a problem being chased via the node-red group) note every thing runs for 8 hours before Mqtt fails. however as you can see 06:05:44 Mqtt connects but at this point blynk is not connected and even after 50 minutes blynk fails to reconnect.

[tzapu]

maybe blynk was already dead because of other reasons
i ve added a local installation of the blynk server, together with a remote node red and am pushing quite a bit of data through it to see what happens, maybe we ll get to the bottom of this.
so far for me it auto recovered from a closed terminal that killed the blynk server...

[Toshibass]

Note. MQTT disconnects issue has been rectified in the latest node-red update v0.13.3

[tzapu]

so it means we couldn t track this because it was in node red ? weird :)

[qm3ster]

@tzapu this should probably be closed now?
And what are those light blue nodes in the middle, with gauges on them?

@qm3ster emoncms.org nodes

also, disconnection happened to me again, even with 0.13.3

at some point soon, i will advise everyone to move to the websockets version of this
it s just a lot more stable and a lot faster
