# Cloudflare Error 1023: Could not find host

**Code:** `1023` · **Category:** Cloudflare · **Seen on:** Cloudflare

Cloudflare can’t find the host — typically a zone that’s inactive or a custom hostname/SSL for SaaS not set up.

## Meaning

Appears for zones pending activation, deleted zones, or SaaS custom hostnames not provisioned on the provider’s zone.

## Common causes

- Zone not active
- Custom hostname not configured (Cloudflare for SaaS)
- DNS cached from an old setup

## Quick fix

1. Verify the zone is active
2. Add/validate the custom hostname at the SaaS provider
3. Wait for DNS caches to expire

## Detailed fix by platform

### Shell

1. `dig +short example.com @1.1.1.1`

## How to diagnose

1. **Zone** — Status
2. **SaaS** — Custom hostname status
