Problems with Certs

When I try to make a call to my DO PostGres database from my DO App, I get an error: {“code”:“SELF_SIGNED_CERT_IN_CHAIN”}

I’ve got the CA-Cert setup in my database connection:

databaseConfig = {
    host: process.env.DBhost,
    port: process.env.DBport,
    database: process.env.database,
    user: process.env.DBusername,
    password: process.env.DBpassword,
    ssl: {
        rejectUnauthorized: true,
        ca: process.env.CA_CERT,
    sslmode: 'require'

Here are the summaries of what I have working: Build & Deploy: Local System: Good DO Hosted App: Good

Non-PostGres Pinging Request: Local System: Good DO Hosted App: Good

DO PostGres Pinging Request: Local System: Good DO Hosted App: Fail {“code”:“SELF_SIGNED_CERT_IN_CHAIN”}

This suggests that the DO Host alone can’t connect for some reason.

I’ve tried changing node middleware - no effect.

I’ve tried the VPC approach but I can’t seem to add my App to it and it shouldn’t matter anyway.

I’ve tried to add my own Let’s Encrypt certs to the DO App, but don’t have Sudo access and it shouldn’t matter anyway.

What do I need to do to make this work?

Got it to work! Needed the SSL cert in file form, not in an environment variable.

You are correct, you’ll need your SSL cet in file form.

Additionally, regarding App Platform, if anyone stublmes upon this question, If you are using the DigitalOCean App Platform this is all done automatically. With the App Platform, DigitalOcean creates, manages, and renews your SSL certificates automatically.
