连接到Heroku Postgres数据库时出现CertificateUnknown错误

Question

所以,我在从SQL Server迁移到PostgreSQL的中间,我建设迁移期间的临时解决方案,让我的ASP.NET应用程序连接到我的Heroku Postgres数据库,并利用实体框架等.

到目前为止,我已经设法从pgAdmin III连接到数据库的Windows没有问题,但是当从ASP.NET应用程序连接时,我收到此错误:

CertificateUnknown:不接受服务器证书.链状态:已处理证书链,但终止于信任提供程序不信任的根证书..证书中不存在指定的主机名.

我仍然是heroku的新手,但是为什么我可以使用与我的ASP.NET应用程序相同的设置从pgAdmin连接它没有意义,但它在应用程序本身中不起作用.

使用Npgsql 3.1.5尝试在连接字符串中使用"Trust Server Certificate = true".连接字符串示例:

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