Cloudflare aur DNS Troubleshooting

Yahan Ahmed website ke do real incidents ki documentation Roman Urdu mein rakhi gayi hai. Maqsad ye hai ke agar future mein koi website mobile data par khul rahi ho lekin Wi-Fi par na khule, to root-cause investigation repeat na karni pade.

Incidents

Case	Symptom	Status
Naye custom domain par DNS_PROBE error	Website deploy thi lekin kuch DNS resolvers par address nahi mil raha tha	Resolved
Wi-Fi par website nahi, mobile data par working	Laptop aur phone Wi-Fi par fail, phone mobile data par successful	Resolved; precise router/ISP cause unconfirmed

Architecture

• Website: https://ahmed.digitalstudio.ltd/
• Hosting: Cloudflare Worker ahmed-starlight
• Framework: Astro + Starlight
• DNS zone: digitalstudio.ltd (Cloudflare authoritative DNS)
• Fallback: https://ahmed-starlight.admin-1c5.workers.dev/
• Cloudflare Tunnel: Is website ke liye required nahi. Ye directly Worker Custom Domain par serve hoti hai.

Issue diagnose karne ka order

1. Pehle URL ka spelling check karein: digitalstudio.ltd, datastudio.ltd nahi.
2. Cloudflare dashboard mein Worker aur Custom Domain mapping verify karein.
3. Authoritative nameservers aur public resolvers ke A/AAAA results compare karein.
4. Agar mobile data kaam karta ho aur Wi-Fi nahi, to router/ISP/local DNS ko alag investigate karein.
5. DNS resolve hone ke baad HTTPS status aur SSL certificate check karein.
6. Kisi setting ko randomly change na karein; har change ke baad result record karein.

Note: Dono issues DNS resolution se related thay; Worker code, Cloudflare Tunnel ya website content ka fault confirm nahi hua tha.
