Custom domain setup

Mainland China domains： Read Custom domain first; match the in-product Custom domain notice dialog — complete ICP filing and Tencent Cloud access filing.

1. Open SEO settings

• In the left sidebar, click SEO
• Under Domain, click + Custom domain

2. Start setup

• For a subdomain, check I want to use a subdomain
• Click Continue

4. Choose provider

• Pick your registrar if listed
• Otherwise scroll to Go to our manual setup

5. DNS records

• On Configure your domain manually by adding these records, add two CNAME records:
• First：
• RECORD TYPE: CNAME
• HOST NAME: www
• REQUIRED VALUE: [target from superun]
• Second：
• RECORD TYPE: CNAME
• HOST NAME: @
• REQUIRED VALUE: [target from superun]
• Copy values with Copy
• Add records at your DNS host (Alibaba Cloud, Tencent Cloud, etc.)

6. Confirm DNS

• After adding records at your provider, return to superun
• Click I have added 2/2 records above to my domain’s provider

7. Finish

• Wait for DNS verification (minutes to hours)
• When successful, click Done

• DNS can take up to 48 hours to propagate globally
• Add both CNAME records correctly
• SSL is provisioned automatically
• If the site does not load, recheck DNS

• Provider not listed： Use manual setup (Go to our manual setup)
• DNS added but site down： Wait for propagation (up to 48 hours)
• SSL pending： Certificates apply after DNS is valid
• 301 redirects： Configure at your registrar/DNS host, not in superun

​

Troubleshooting

​

Domain binding fails

• GoDaddy apex domain cannot use CNAME directly
• Domain resolves but redirects to superun homepage

1. Cloudflare： Point nameservers to Cloudflare, then bind via superun

• Update nameservers at your registrar
• Complete binding in superun with Cloudflare

2. Ask AI after consulting：

 After binding, my domain goes to the superun homepage — what might be wrong and what should change?

• Confirm the correct domain in main flow and ask the AI to update config

1. Move nameservers to Cloudflare at registrar
2. Bind domain in superun via Cloudflare
3. Wait for DNS (minutes to hours)
