Here is my connection code :
this.connection = mysql.createConnection({
host: 'xxxx.db.ondigitalocean.com',
user: 'doadmin',
port: 25060,
password: 'xxxx',
dialect: 'mysql',
force: true,
ssl: {
cert: fs.readFileSync(__dirname + '/ca-certificate.crt'),
}
});
Here is the error im getting
(node:5676) UnhandledPromiseRejectionWarning: Error: self signed certificate in certificate chain

I’m experiencing the exact same issue. The certificate provided by DO doesn’t make a connection possible from my local computer to the managed DB. I’d really appreciate some input on how to use it within a node.js application and one of the available mysql drivers.
So far I couldn’t find any solutions online, which unfortunately prevents me from actually using DO :/
ssl: {
ca: fs.readFileSync(__dirname + '/ca-certificate.crt'),
}
Change cert attribute to ca You can even add rejectUnauthorized: true
Hi @nickynick,
Usually when experiencing this issue is when you are using a SELF SIGNED certificate, is that correct?
If that’s the case, add NODE_TLS_REJECT_UNAUTHORIZED='0' as an environment variable wherever you are running node or running node directly with NODE_TLS_REJECT_UNAUTHORIZED='0' node app.js
This instructs Node to allow untrusted certificates (untrusted = not verified by a certificate authority)
I would not recommend setting this environment variable in production as your application would not be trusted by users. You can use free Let’s Encrypt certificates.
