My custom domain is hosted on Cloudflare with the proxy (orange cloud) enabled. It has been working for over a month, but today both domains suddenly stopped working.
The console shows the Zeabur platform domain as PROVISIONING. I tried deleting and re-adding both the custom domain and the generated platform domain. Now, the platform domain is intermittently available, while the custom domain either shows Cloudflare's Error code 521: Web server is down or the Zeabur platform shows 404: HOSTNAME_NOT_FOUND, indicating the domain or path could not be found.
