Hi everyone,

My GitHub Pages site (repo: ZouYue123321/nihao) uses the custom domain melodyzpm.com. The HTTPS certificate has been stuck at "Detected a change to DNS settings. Requesting a new certificate." (state: dns_changed) for more than two days, so "Enforce HTTPS" can't be enabled and HTTPS still serves the default *.github.io certificate.

What I've checked:

• Apex A records: 185.199.108.153, 185.199.109.153, 185.199.110.153, 185.199.111.153 (nothing else on @)
• No AAAA, CAA, ALIAS or URL-forwarding records
• www CNAME -> zouyue123321.github.io
• CNAME file exists in main and contains melodyzpm.com
• DNS provider (Alibaba Cloud) reports the config as correct
• Removed and re-added the custom domain on Oct 18 and Oct 19, 2026; no certificate ever appears in certificate transparency logs

A support ticket was closed because my account only has community support. Could a GitHub staff member please check or re-trigger certificate provisioning for melodyzpm.com? Any other ideas are welcome too.

Thanks!
