    You can try set your connection string in config with

    Encrypt = False

    or

    Encrypt = True; Trust Server Certificate=true;

    SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.)

    It's a SSL error. Seems you try to establish an encrypted connection, but the certificate for encryption isn't trusted.

    See https://learn.microsoft.com/en-us/troubleshoot/sql/database-engine/connect/certificate-chain-not-trusted?tabs=ole-db-driver-19

    Hi @pankaj prajapati,

    Agree with them. I'm not sure about your OS, I'd still like you to read the article. This applies to Windows Server 2019 and Windows Server 2016. If you are not using either of these, you can also upgrade your OS and install the latest patches.

    Best regards,

    Seeya

    It's an SSL error and the certificate you are using is not encrypted.

    This error that you are getting can be resolved and follow these steps: In Certificate Snap, Expand trusted root certification authorities. In Certificates Select All tasks> Import Under import there will be a certificate dialog box then click on Next and select finish
