Appearance
SSL Certificates (15-Year CA)
GuildUSA utilizes Cloudflare Origin Certificates to eliminate the technical debt associated with 90-day Let's Encrypt / Certbot renewal cycles.
Architecture
Both the Production and Sandbox VPS instances are secured with a Wildcard Certificate (guildusa.com and *.guildusa.com) valid until May 2041.
Nginx Implementation
The certificates physically live on the servers at:
/etc/ssl/cloudflare/cert.pem/etc/ssl/cloudflare/key.pem
If a new Nginx server block is created, it must point to these paths and explicitly utilize ssl_protocols TLSv1.2 TLSv1.3;. Certbot must not be run on these servers, as it will conflict with Cloudflare's strict proxy routing.
