DO Manage PostgreSQL connection with ASP.NET 5 EF Core, connection string help

**Hello,

I have a Ubuntu droplet running my app, and am also running localy from a MacBook, and I am having truble connecting to it.**

Here is the string I am using:

“Host=db-postgresql-fra1-XXXx-do-XXXx-XXX-0.b.db.ondigitalocean.com; Port=25060; Database=XXXX; Username=XXXX; Password=XXXXX; SslMode=Require”

This is the error i get: The remote certificate was rejected by the provided RemoteCertificateValidationCallback

How do I specify the path to the CA Cert, and can I just have it in the project?

Thanks for any help.

Hi there,

There are a few ways to do that:

  • Specify the Client Certificate directly in the connection string parameter.
  • Define a PGSSLCERT environment variable.
  • Create a ~/.postgresql/postgresql.crt file with your CA certificate.

For more information I could suggest taking a look at the docs here:

Let me know if you have any questions.

Best,

Bobby
