Prisma Database Connection Timeout

Your Prisma database queries timeout with 'Can't reach database server' or connection pool exhaustion errors. Application queries fail or hang indefinitely.

Connection timeouts happen when Prisma cannot establish a connection to the database within the configured time limit, typically due to network issues, database overload, or misconfigured connection parameters.

Error Messages You Might See

Can't reach database server at `localhost:5432` Timeout acquiring a connection from the pool Cannection timed out Fatal error: remaining connection slots are reserved
Can't reach database server at `localhost:5432`Timeout acquiring a connection from the poolCannection timed outFatal error: remaining connection slots are reserved

Common Causes

  1. Database server down, unreachable, or not properly started
  2. CONNECTION_LIMIT too low for concurrent requests (default 10)
  3. Network firewall blocking database port access
  4. DATABASE_URL malformed or pointing to wrong database
  5. Too many open connections overwhelming the pool

How to Fix It

Verify database: Ensure your PostgreSQL or MySQL server is running. Test connection with psql -c "select 1".

Check DATABASE_URL: Format should be postgresql://user:password@host:port/database?schema=public. Test with any URL validator.

Increase pool size: In .env, add PRISMA_CONNECTION_LIMIT=20 for higher concurrency.

Add connection timeout: Set DATABASE_URL=...?connect_timeout=10 to extend timeout from default 5 seconds.
