我目前有一个不和谐的机器人与Nextcord.py与工作数据库上的CockroachDB。我设法在Heroku上托管和部署了机器人，命令可以工作，但我似乎无法让数据库工作。
Heroku日志中的错误行是2023-06-14T10:29:55.300444+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch
当我尝试使用Worker而不是Web时，当我尝试一个命令时，我会得到这个错误。

2023-06-14T10:46:44.323804+00:00 app[worker.1]: psycopg2.OperationalError: connection to server at "enter server here" (IP), port 32481 failed: Connection timed out

我使用Psycopg 2手动连接到CockroachDB，代码如下：

conn = psycopg2.connect(
        host = os.getenv('HOST'),
        port = os.getenv('PORT'),
        database = os.getenv('DATABASE'),
        user = os.getenv('USER'),
        password = os.getenv('PASSWORD'),
        sslmode = os.getenv('SSLMODE')
        )

其中环境变量为：

HOST=calmer-herring-5909.7tc.cockroachlabs.cloud
PORT=*port*
DATABASE=*database*
USER=*user*
PASSWORD=*password*
SSLMODE=verify-full

这是一个Heroku相关的问题吗？我看不出哪里出了问题。谢谢！
