this is how i am connecting to db i really need to get this service up quickly : (

𝐗-𝐥𝐞𝐦•2mo ago

@Anubhav Make sure you're giving enough time for the private network to initialize.

Currently, private networks take up to 3 seconds to initialize on deploy. ... If you experience errors like those above, consider implementing a sleep or other wait mechanism in your app, before attempting to connect.

https://docs.railway.app/guides/private-networking#initialization-time

Anubhav•2mo ago

i am using poetry run start does it will support sleep? sleep 3 && poetry run start right?

𝐗-𝐥𝐞𝐦•2mo ago

I'm not familiar with poetry sorry so I'm not sure what the command would be.

Anubhav•2mo ago

: (

𝐗-𝐥𝐞𝐦•2mo ago

In my program I just check to see if the DB connection failed and then try again in 5 seconds. That fixed it for me.

Anubhav•2mo ago

ok i just deployed with sleep 3 hoping to work i have added asyncio.sleep at my connect method so it waits hopefully it works

𝐗-𝐥𝐞𝐦•2mo ago

Does this work locally? I'm not seeing in your code where you're getting the env variable (I'm assuming you're using an env variable to pass your DB private URL to your application).

class MyBot(commands.Bot):

    def __init__(self, *, intents: discord.Intents):

        )

        self.coc_client: coc.Client = coc_client

        self.db = Database(dsn=Core.DATABSE_URL)
        await self.db.connect()

it does work locally and works perfectly : ( i am not able to establish connection on railway for some reason

𝐗-𝐥𝐞𝐦•2mo ago

If you print out DevCreds.DEV_SITE_PASSWORD does it print out what you expect?

Anubhav•2mo ago

yep its another api creds

𝐗-𝐥𝐞𝐦•2mo ago

Also the private url isn't just the password. It's the full connecction string.

Anubhav•2mo ago

i referenced it

𝐗-𝐥𝐞𝐦•2mo ago

Does it work locally if you use the public connection string?
