DNS Setup

Point your domain to the VPS.

Cloudflare#

1. Go to dash.cloudflare.com → your domain → DNS → Records
2. Add an A record:
   • Name: @ (root) or api (subdomain) or api.trader (nested subdomain)
   • IPv4: VPS_IP
   • Proxy: Grey cloud (DNS only) — important for Certbot to work
   • TTL: Auto
3. After SSL is set up, you can optionally switch to orange cloud (Cloudflare proxy)

Other DNS providers (Namecheap, GoDaddy, etc.)#

Add an A record pointing your domain/subdomain to VPS_IP. TTL: automatic or 300.
