I'm trying to connect my MySQL database to my Laravel API deployed on Railway. When I use the internal URL or host provided by Railway (e.g., DB_HOST set to the internal address like mysql.internal), I encounter a "connection refused" error. However, when I use the external or public URL (like autorack.proxy.rlwy.net), the connection works successfully. It seems that Laravel cannot resolve or access the internal database host, while the external/public host works without issues. Any guidance on why this might be happening or how to properly configure the internal connection would be appreciated.
