Nginx & Domain Setup

I recently rebuilt my VPS and lost the previous Nginx configuration that let my domain resolve through an Anti-DDoS protected IP. Right now the protected IP is active on Namecheap, the origin IP is registered in the mitigation panel, yet nothing reaches the server. I’m certain the snag is in Nginx, because the DNS side of the protected IP still looks identical to the old working snapshot.

What I need from you:
• Recreate a clean, production-ready Nginx config that listens on the origin IP, forwards traffic through the protected IP, and serves both my frontend and backend apps over the correct sub-paths or ports.
• Update any necessary DNS or A-record details on Namecheap so the domain and its “www” variant resolve only to the protected IP.
• Verify that the frontend builds, the API responds, and both load without mixed-content or certificate errors.

I’ll share root SSH access, the Anti-DDoS control-panel credentials, and the domain zone records so you can work end-to-end. When I can open the site in a browser, hit the API route, and see the correct headers coming from Nginx, the job is done and I’ll release payment immediately.
