heroku pg:psql无法正常工作

我尝试通过运行命令“heroku pg:psql”连接到我的应用程序的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?

我还尝试使用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?

任何人都可以告诉我如何修复这些错误并正确连接到我的数据库.
提前致谢!

最佳答案 试试这个:

heroku pg:psql DATABASE_URL
