Hello,

I want to connect my postgress database on Digital Ocean to my airtable import. I choose the option to add a datasource and get the error “self signed certificate in chain”. I uploaded a certificate from digital ocean, yet that doesn’t solve the problem. Any suggestions on how to approach this problem?

Pls verify if the key and credentials you have work with any other Database client to begin with like Dbeaver, tableplus etc.
