Are you hosting Supabase or are you connecting an external instance?

connecting external instance

i already have a project in supabase but it is still empty

is this correct

You need to redeploy your service to use the variables.

but where do i get the Database_URL tho

it saids pooler something

Go to your project dashboard and hover over the URL.

this?

so it is the same with Supabase_url variable?

I don't know what you put.

If it's the same, then it's the same.

The URL should start with postgresql://.

It should be called "Direct connection string" in Supabase dashboard.

The string you shared is a Direct Connection URL. While it looks correct, it will likely cause your app on Railway to crash with a Network is unreachable or ENETUNREACH error.

it says this

What said that...

it says that railway only support Ipv4 connection but supabase uses IPv6

is it true tho

does railway now supports Ipv6? since i researched again and it said yes

That costs extra money, can't you just enable outbound IPv6 on the railway service?

outbound ipv6 is a feature flag option

https://railway.com/account/feature-flags

so i dont need to change the port 5432 to 6543

or change the pooler in supabase

Oh cool. Didn’t know it’s now a feature flag.

owh damn

damn tysm!

lastly do i need to remove the syntax ${{}} in railway

If they are reference variables, no. You need to keep them.

how about for Supabase_URL?

I don't know how you structured your project. If it's a reference variable, then you need the ${{}} syntax.
