Hi,

I'm experiencing an issue with Private Networking between two services in my project.

Setup:

• Service 1: Next.js app with Private Networking enabled
• Service 2: MySQL database with Private Networking enabled
• Both services show green checkmark and "Ready to talk privately"

Problem: My Next.js app cannot reach the MySQL database using the internal URL (mysql.railway.internal:3306). The connection fails with:

Can't reach database server at mysql.railway.internal:3306

However, when I use the public URL (MYSQL_PUBLIC_URL), the connection works perfectly.

Context: This issue started after I duplicated my workspace to create a "dev" environment and then deleted that duplicate project. Before this, the internal networking was working fine.

What I've tried:

• Verified Private Networking is enabled on both services
• Restarted both services
• Redeployed both services
• Deleted and recreated the DATABASE_URL variable

Could you please investigate why the private network connection is failing between these services?

Thank you.
