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！
