I deployed the Sequin template https://railway.com/template/TXSiv2 and am trying to connect to my Supabase Cloud database but am getting this error

Failed to connect to database. Please check connection details. (error=connection not available and request was dropped from queue after 2000ms. This means requests are coming in and your connection pool cannot serve them fast enough. You can address this by: 1. Ensuring your database is available and that you can connect to it 2. Tracking down slow queries and making sure they are running fast enough 3. Increasing the poolsize (although this increases resource consumption) 4. Allowing requests to wait longer by increasing :queuetarget and :queueinterval See DBConnection.startlink/2 for more information )

I verified the connection works fine on Sequin Cloud + PgAdmin 4, so I assume there's a networking issue with Railway or misconfiguration in the template.
