Deploy failed: no response from server

General

Hi.

After installing Node Red V 0.20.3 I have some troubles..
the message:

deploy failed: no response from server

keep appearing when i hit Deploy and i have to reload my browser and then it works fine to Deploy again for some times but the problem returns after a short while after some work and switching between Node red and Ui-dashboard
I use HTTPS to connect to Node Red an UI.

Anyone who has been troubled with the same issue?

2

what does the log say? What version of nodejs are you using?

3 
Node-RED version: v0.20.3
Node.js  version: v10.15.3
Dashboard version 2.14.0

The console is not showing any error in log but the console in my Chrome browser shows this message:

net::ERR_CERT_AUTHORITY_INVALID

I think perhaps that it is my Chrome browser that is the root of my problem and the fact that i use a SSL certificate that causes a warning in chrome?

seems like the problem was solved after using a new certificate from letsencrypt.

No, I get the same now and again (every 10th deployment?) on 0.20.3, and I’m on virgin HTTP.

I don’t have to reload though, just try again.

I see this issue with Node-RED version 0.20.3

html, body { height: 100%; box-sizing: border-box; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; } html { overflow: hidden; } body { font-family: Segoe UI, Helvetica Neue, Helvetica, Arial, Verdana; color: #222222; background-color: #ffffff; font-size: 14px; word-break: break-word; margin:0; padding: 5px; box-sizing: border-box; overflow: auto; } body.invalid { background-color: #ffc; } P { line-height: 1.5em; margin: 0; } body.watermark { color: #999999; font-style: italic; } img { max-width: 100%; } a, a:visited { color: #007acc; }

  1. Login to nodered.

  2. Import the following flows and deploy.

Sample flow:

[{"id":"52cfbedb.214ec","type":"inject","z":"109eeae9.2cf315","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":200,"y":120,"wires":[["c1174706.cb4cc8"]]},{"id":"c1174706.cb4cc8","type":"function","z":"109eeae9.2cf315","name":"","func":"msg.topic = "Insert into stu;";\nreturn msg;","outputs":1,"noerr":0,"x":420,"y":160,"wires":[["dbf2cb16.d97d48"]]},{"id":"dbf2cb16.d97d48","type":"debug","z":"109eeae9.2cf315","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":660,"y":160,"wires":}]

Have you seen if you have the same issue with the latest version of Node-RED?

What version of nodejs are you using?

node -v v8.15.1

I'm yet to test Node-RED v0.20.7

I am getting this error when I am trying to Insert the data coming from real-time sensors in JSON format.
All the other queries except the Insert query is running fine.

Below is the Insert query I am using inside my template node:

INSERT INTO aress_support_sensor (mac_id, timestamp, temperature, humidity, air_quality, air_quality_value, loudness, sensor_buzzed)
VALUES ("{{{payload.0}}}","{{{payload.1}}}","{{{payload.2}}}","{{{payload.3}}}","{{{payload.4}}}","{{{payload.5}}}","{{{payload.6}}}","{{{payload.7}}}");

This query ran once and the deployment was successful. But immediately after 10 15 minutes, when I updated the flow and deployed it, the deployment was failing with this error: " [Deploy failed: no response from server]"

I am unable to figure out the issue as I have tried all the possible ways to use the Insert query.
