I am using SQL Server (SQL EXPRESS) 2005 9.0.3042
I have poured through lots of examples.
Made sure TCP port 1433 open for all IP.
Made sure browser is started
Tried all kinds of config settings
using tedious or mssql
Just trying to find something that will work !!
But all I get is the following errors
ConnectionError: Failed to connect to localhost:1433 - Cannot call write after a stream was destroyed
at ConnectionError (C:\git\adv_energy\sql_node_js\node_modules\tedious\lib\errors.js:13:12)

Hi all I am learning Nodejs. I am uploading file to AZURE server, but getting the below error after every 3-4 minutes. Anyone have the solution for this?
The error is ->
Error: read ECONNRESET
at TCP.onStreamRead (internal/stream_base_commons.js:111:27)
Emitted 'error' event at:

"ECONNRESET" means the other side of the TCP conversation abruptly closed its end of the connection. This is most probably due to one or more application protocol errors. You could look at the API server logs to see if it complains about something.
Glad #RakeshSaini that you identified the error which was in the connection waiting limit in the MySQL and for fixing the issue.
I'm trying to setup a Node.js Websocket server over at my webhost (Namecheap). However, I am getting this error:
events.js:292
throw er; // Unhandled 'error' event

The code for the client and server came from here:
https://github.com/websockets/ws#Simple server
https://github.com/websockets/ws#sending-and-receiving-text-data
with ws://www.host.com/path changed to ws://<mydomainname>/<dir1>/<dir2>
Both client and server code runs properly when run locally. Http related code runs properly when used on my webhost. I am trying to get the client code to run locally and connect via websockets to my server hosted at Namecheap.
I suspect something related to the server is preventing connection. I'd ask support but I doubt if they can resolve this. Maybe there's a locked feature or something? Is there something else I could have missed?
Websockets cannot work on Namecheap's hosted servers. Their incoming ports are blocked and cannot be opened for security reasons per their customer's support.
If anyone is looking for a solution just in case, try out a Heroku free account.
I'm pretty sure I've exhausted all methods here, followed the first 3 pages of Google and near every similar question here, and I am getting sick of reading every response to this "have you downloaded MongoDB?".
YES, it is downloaded, and running, and connectable from Robo3T and CLI mongo.
MongoDB shell version v4.0.2
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 4.0.2
YES, it was downloaded/installed using the recommended setup from source -- ie, home brew, brew services etc.
Jamies-MacBook-Pro:api jamiepoole$ brew services list
Name Status User Plist
mongodb started jamiepoole /Users/jamiepoole/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
YES, I have tried connecting with localhost, 127.0.0.1, hell even the computer hostname / Jamies-MacBook-Pro.local
I have no doubt I'm doing something stupid or missed something simple, but I am pretty certain its not that.
const Database = Mongoose.connect('mongodb://localhost:27071/myproject');
---
I replaced project details from the below with ... -- so this isn't a setting / in the code.

At this point any help at all would be amazing. Seems like such a simple error but can't find any help anywhere.
Cheers
You have defined wrong MongoDB port in your code while your CLI is connecting to the right port which 27017. You can edit the code as follows
const Database = Mongoose.connect('mongodb://localhost:27017/myproject');
I have a MongoDB Cluster in MongoDB Atlas and I use this MONGO_URI that they provided to connect to it. The format is something like this:
mongodb://<USERNAME>:<PASSWORD>#cluster0-shard-00-00-nnn.gcp.mongodb.net:27017,cluster0-shard-00-01-nnn.gcp.mongodb.net:27017,cluster0-shard-00-02-nnn.gcp.mongodb.net:27017/test?ssl=true&replicaSet=Cluster0-shard-0&authSource=admin&retryWrites=true
When I run my node.js program locally, I can read and write the database. However, when I deploy to google cloud, I'm having connecting to it. This is what I see in Google Console:
Mongoose connection "error" event fired with:
{ MongoError: connection 5 to cluster0-shard-00-02-32tq4.mongodb.net:27017 closed

I've tried to add allow-mongodb to firewall with protocols and ports as tcp:27017, direction ingress, IP ranges 0.0.0.0/0 and it's still not working. Can someone tell me what I'm missing here?
P.S I'm kinda suspecting that I have to add my mongodb cluster's IP to firewall as well though I'm not sure
I am having this problem while connecting the elasticsearch connections.
var elasticsearch = require('elasticsearch');
var client = new elasticsearch.Client({ host: 'localhost:9200',
log: 'trace'});

I understand this question is quite old but I wanted to share how you can solve this problem.
If you are locally using elasticsearch
First thing you must do is running elasticsearch on your machine.
Error: Request error, retrying -- connect ECONNREFUSED 127.0.0.1:9200
Because above message indicates that you're not running elasticsearch locally.
So, visit the link and follow the insturction.
Docker environment
It gets much trickier here.
First, follow the instruction here.
And in case you're using node.js elasticsearch client, you have to specify elasticsearch host as 172.24.0.1.
If you use container_name or private IP of container in docker-compose.yml, it won't work.
In case of Docker Container Environment after changing from http://localhost:9200 to http://ipaddress:9200 in docker-compose.yml
please change the following live in docker-compose.yml that is related to CORS
Change this
** http.cors.allow-origin=/https?://localhost(:[0-9]+)?/ **
into this
*- http.cors.allow-origin= **
