heroku pg：psql不起作用

Question

我试图通过运行命令“ heroku pg：psql”连接到我在heroku上的应用程序的Postgres数据库，并收到以下错误消息：

psql: could not connect to server: Connection timed out (0x0000274C/10060)
    Is the server running on host "URL.com"(IP address)  and accepting
    TCP/IP connections on port 5432?

我也尝试使用Pgadmin连接并得到错误：

Server doesn't listen. Is the server running on host "URL.com" (IP address) and accepting
    TCP/IP connections on port 5432?

谁能告诉我如何解决这些错误并正确连接到我的数据库。提前致谢！
