Certificate error when connecting to SQL Server

Question

When trying to connect to SQL Server, I get the following error:

(node:9364) UnhandledPromiseRejectionWarning: ConnectionError: Failed to connect to 10.120.6.11:1433 - self signed certificate

When I use SQL Server 2014, it works normally.

Note: You need a vpn to connect.

Code:

const config = {
  port: parseInt(process.env.DB_PORT, 10),
  server: process.env.DB_HOST,
  user: process.env.DB_USER,
  password: process.env.DB_PASS,
  database: process.env.DB_Database,
  stream: false,
  options: {
    trustedConnection: true,
    encrypt: true,
    enableArithAbort: true,
    trustServerCertificate: false,

  },
}

sql.connect(config).then(pool => {
  if (pool.connecting) {
    console.log('Connecting to the database...')
  }
  if (pool.connected) {
    console.log('Connected to SQL Server')
  }
})

Answer 1

I had the same error message (Failed to connect to xxx:1433 - self signed certificate). Then I used trustServerCertificate: true. This fixed the error for me.

Answer 2

I encountered the same problem on my project. I manage to solve the problem by adding trustServerCertificate: true

Example (NestJS and TypeORM usage):

TypeOrmModule.forRoot({
  type: 'mssql',
  host: 'localhost\\SQLEXPRESS',
  username: 'sa',
  password: 'root',
  database: 'DB',
  entities: [__dirname + '/**/*.entity{.ts,.js}'],
  synchronize: true,
  extra: {
    trustServerCertificate: true,
  }
}),

Answer 3

What works with me, with the full script:

var express = require('express');
var app = express();
app.get('/', function (req, res) {
    var sql = require("mssql");
    // config for your database
    var config = {
        user: 'sa',
        password: 'P@ssw0rd',
        server: 'WIN-N4J1057LVFV', 
        database: 'WIN-PAK_ALL',
        synchronize: true,
        trustServerCertificate: true,
    };
    // connect to your database
    sql.connect(config, function (err) {
        if (err) console.log(err);
        // create Request object
        var request = new sql.Request();
        // query to the database and get the records
        request.query('select * from cardHistory', function (err, recordset) {
            if (err) console.log(err)
            // send records as a response
            res.send(recordset);
        });
    });
});
var server = app.listen(5000, function () {
    console.log('Server is running..');
});
