Log: flex.ai is officially deployed to the internet!

Ran into a classic cloud networking headache during the setup. Every time I launched the Caddy Docker container, the logs showed a connection timeout while trying to provision the SSL certificate.

At first, I was convinced my subnet security rules were the issue. But after digging through OCI’s notoriously confusing interface, I finally found the real culprit: a hidden option to “Connect public subnet to internet.” It turns out the subnet wasn’t properly routed to the internet gateway.

Once that was enabled, everything clicked instantly. Let’s Encrypt passed, Caddy secured the domain, and the API is now fully live over HTTPS.
