Craft Server Not Found or Won't Load

Workaround available Web, Windows, macOS Updated October 21, 2026

Quick answer

'Server Not Found' or a Craft web/Windows app that won't load is usually a VPN, proxy, ad blocker or company firewall blocking Craft's domains. Disable the tool or allowlist *.craft.do, or try another network.

Most likely fix: Disable blockers temporarily.

Symptoms

Craft shows 'Server Not Found', pages stay blank, the web app won't open, or link previews say 'Failed to fetch data'.

Why it happens

  • VPN, proxy or DNS filter blocking Craft
  • Ad blocker or privacy extension (AdGuard, Hush, Plume Guard)
  • Corporate firewall not allowing Craft domains

How to fix it

Try these in order — the most common fix is first.

  1. 1. Disable blockers temporarily

    1. Turn off VPN, proxy, AdGuard or Little Snitch
    2. In the browser, open a private window with extensions off

  2. 2. Allowlist Craft

    1. Add api.craft.do, docs.craft.do and res.craft.do (or *.craft.do) to the tool's allowlist
    2. At work, ask IT to allow these domains

  3. 3. Try another network

    1. Switch to mobile hotspot or home Wi-Fi
    2. If it fails on every network, contact Craft support
