[NODE v18] Failed to connect to {server} - socket hang up (code: ESOCKET)

Everything works in Node v14 and v16 (haven’t used v17 as it isn’t LTS or a candidate for it). This issue seems to only pop up with the latest current v18.

Note: sensitive data has been omitted.

Actual behaviour:

Configuration:

The connection is handled by sequelize.

{
    username: '[OMITTED]',
    password: '{OMITTED]',
    host: '{OMITTED]',
    logging: true,
}

I have tried passing recommended options but to no avail.

options: {
    keepAlive: true,
    encrypt: true,
    enableArithAbort: true,
}

As previously mentioned: this works fine up to Node v16

Software versions

• NodeJS: 18.4.0
• node-mssql: 8.1.2
• tedious: 14.5.x | 14.6.x
• sequelize: 6.20.1
• SQL Server: SQL Server 2016 Service Pack 1 CU11 (13.0.4528.0)

Actually, I now found a way to workaround this, but I’d only use it if there’s really no way to get a more secure certificate installed:

    cryptoCredentialsDetails: {
      ciphers: 'DEFAULT@SECLEVEL=0',
    }

Any other security level higher than 0 does change the list of sigalgs that are sent by OpenSSL in a way that makes the TLS connection fail.

Hey @arthurschreiber,

I found a relatively simple way to reproduce using an AWS EC2 instance:

1. Create an EC2 instance from the standard “Quick Start” AMIs using “Microsoft Windows Server 2012 R2 with SQL Server 2016 Standard” (I used size c3.large)
2. RDP onto it and install desired node version for testing
3. Create a temp dir, e.g. C:\Tmp\ and copy the index.js below into the dir (** adjust the password and domain to match the instance’s Administrator password)
4. Launch a command prompt into the C:\Tmp dir and run npm install tedious, then run node .

//index.js
const { Connection, Request } = require('tedious');

const config = {
  server: "localhost",
  options: {
    trustServerCertificate: true,
  },
  authentication: {
    type: "ntlm",
    options: {
      userName: 'Administrator',
      password: '***redacted***',
      domain: 'ip-172-31-22-11.ec2.internal', // change this!
    }
  }
};

const connection = new Connection(config);

function executeStatement() {
  request = new Request(
    'select * FROM sys.databases',
    function (err, rowCount) {
      if (err) {
        console.log(err);
      } else {
        console.log(rowCount + ' rows');
      }
    });

  request.on('row', function (columns) {
    console.log(columns[0]);
  });

  connection.execSql(request);
}

// Setup event handler when the connection is established. 
connection.on('connect', function (err) {
  if (err) {
    console.log('Error: ', err)
  }
  // If no error, then good to go...
  executeStatement();
});

// Initialize the connection.
connection.connect();

This will succeed (return rows) for node 16.18.0 (latest), and an error for node 17 and later, here is the error I got on node 17.0.0
