連接到Heroku Postgres數據庫時出現CertificateUnknown錯誤

Question

因此，我正在從SQL Server遷移到PostgreSQL，並且正在構建遷移期的臨時解決方案，以允許我的ASP.NET應用程序連接到我的Heroku Postgres數據庫並利用實體框架等

到目前爲止，我已經成功地使用沒有問題連接到從pgAdmin的第三數據庫中的窗口，但是從ASP.NET應用程序連接時，我得到這個錯誤：

CertificateUnknown: Server certificate was not accepted. Chain status: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. . The specified hostname was not present in the certificate.

我對heroku還是比較陌生的，但是爲什麼我可以從pgAdmin連接到與我的ASP相同的設置並沒有任何意義。 NET應用程序，但它不適用於應用程序本身。

隨着3.1.5 Npgsql的嘗試在連接字符串中使用 「信任服務器證書=真」。 連接字符串示例：

Server=[servername];Port=[port];User Id=[username];Password=[password];Database=[databasename];sslmode=Require;Trust Server Certificate=true
