My Next.js front-end and FastAPI back-end run flawlessly in local development, yet the moment I try to push them to my Linux-based VPS the stack refuses to come online. I need an experienced pair of eyes to diagnose and resolve these deployment problems so the site serves traffic reliably from the server. You’ll be working directly on the VPS (SSH access provided) to: • identify what’s blocking the services from starting or staying up • configure whatever is missing or mis-configured (environment variables, reverse proxy, SSL, process manager, etc.) • push a clean deployment that I can reproduce with a short set of commands Acceptance criteria 1. Both the Next.js client (production build) and the FastAPI API become reachable through their intended domains/ports. 2. Application persists across server reboots via a process manager or container solution you set up. 3. A brief text log documents the steps you took so I can redeploy in the future. If you have solid, recent experience deploying Next.js and FastAPI on a Linux VPS, I’m ready to get this fixed right away.
