ssl: {
                ca: fs.readFileSync(__dirname + '/ca-certificate.crt'),
            }

Change cert attribute to ca
You can even add rejectUnauthorized: true

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 :/

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.

Regards,
KDSys
