I am running a node.js server which is using mysql DB. I was working fine but suddenly it has started throwing following error.
Below is the stacktrace of the error:
Error in connecting to DB: Error: Handshake inactivity timeout

Any help is really appreciated.

edit:
Solved my problem. After removing the line
connection.connect(function(err) {
if (err) throw err;
});
I got the raw MySQL error message saying that the login credentials for MySQL are wrong. I already checked my passwort, but din't noticed the wrong username. Very sorry fr my dumb question.
I have a NodeJS / Express app. It was already working fine but know I dont'get a connection any more to MySQL (MariaDB). Always I try to start the app (with pm2) the start failed, because a exception is thrown.
I have already checked if MySQL is running and I also restarted MySQL and NodeJS app and pdated node-mysql. This is my code for connecting to mysql:
//local mysql db connection
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : 'xxx',
database : 'lizenzverwaltung'
});
connection.connect(function(err) {
if (err) throw err;
});
module.exports = connection;
The error message on startup is:

I can start the NodeJS app, but get the following error, as soon, as I try to run a SQL query:

I already searched but didn't found a solution. Do you have any tips? My MySQL server should working fine, PHPMyAdmin and my Wordpress sites are running fine.
Thanks,

Similar issues have been reported, but I can't work around with there solutions.
I have an express.js app using KNEX to connect to a mysql database hosted in Azure.
I can connect to the DB perfectly from console command or mysql workbench.
However, no way to achieve the same from my node app.
My connection object is the same though:
config.knex = require('knex')({
client: 'mysql',
connection: {
host: 'wineserver.mysql.database.azure.com',
user: 'BurgerAndGreenBeans#wineserver',
password: 'FromageDeChevre',
database: 'gdpr',
insecureAuth: true
},
pool: {
min: 0
},
debug: ['ComQueryPacket']
});
Everytime I start the app, I get alternatively either one error or another one:

It seems to be a kind of incompatibility between Node and Azure's mysql server.
Did anyone experienced the same ?
The similar question: Connecting to Azure Database for MySQL in npm/mysql. As #Gary Liu pointed out, you may use pull 1730 for a workaround.
Please modify the package.json as:
"dependencies": {
"knex": "^0.13.0",
"mysql": "git://github.com/mysqljs/mysql#e3e123e9af7c0829a6c1417d911572a75b4a5f95"
}
then, run npm install to install this version.
I am running a server on AWS EC2 instance on ubuntu using node.js and MYSQL.It was working fine for 3 days, suddenly it stopped working.
On Googling i found that was due to lost connection in MYSQL DB. But could not find the exact cause of the fatal.
I am using following code for MYSQL connection
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : process.env.DB_PASSWORD
});
connection.query('USE MY_DB');
And for querying like this
app.get('/user', function(req, res){
connection.query('SELECT * FROM movie', function(err, rows){
var users = {"users" : rows};
res.send(users);
});
});
And log for the fatal:

I want to know the exact issue and the solution. Any help is appreciated.
I am using mysql in Node.js 6.7.0 to get data from database
connection.query('SELECT * FROM table', function(err, results){
if(err){
console.log('Error while performing the database query:', err);
return;
}else{
console.log('Query results:', results);
}
});
I was normally opening the page (which was previously working) when I got an error:
Error while performing the database query: Error: Handshake inactivity
timeout
The server didn't stop running, I refreshed the page and everything is ok...
It never happened before, what does this mean?
This is the full error that I got in the log:
Error while performing the database query: { Error: Handshake inactivity timeout

I am trying to connect to remote mysql(hosted on digitalocean server) and using the db for code in local machine.
When I start the node server and request for data, I get the following error.
{"ERRORMSG":"Something went wrong.{\"code\":\"ENOTFOUND\",\"errno\":\"ENOTFOUND\",\"syscall\":\"getaddrinfo\",\"hostname\":\"http://ip.of.remote.server/\",\"host\":\"http://ip.of.remote.server/\",\"port\":3306,\"fatal\":true}"}
After the first attempt, if I refresh again I get different error
{\"code\":\"PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR\",\"fatal\":false}
Connection is made like this:
connection = mysql.createConnection({
connectionLimit: 10000, //important
host: 'http://ip.of.remote.server/',
user: 'user',
password: 'password',
database: 'db',
multipleStatements: true,
connectionLimit : 100,
waitForConnections : true,
queueLimit :0,
debug : true,
wait_timeout : 28800,
connect_timeout :10
});
Call is made like this
app.get('/WSgetdata', function (req, res) {
var q = "CALL sp_get_data();"
var obj = {};
connection.connect();
connection.query(q, function (err, rows) {
if (err) {
obj.ERRORMSG = JSON.stringify(err);
}
else if((rows[rows.length-1])[0].ERRORSTATUS == 0){
//do something
}
res.end(JSON.stringify(obj))
});
});
What is wrong. It works fine when code and db are on same machine.
Also I have grant access to db from desired IP.
