Fathom GA4 Import Failed or Stuck

Workaround available Web Updated November 13, 2026How we research

Quick answer

Fathom's GA4 import can take up to 48 hours. If it fails, turn off 'Enable user metric reporting' in GA4 property settings and split large histories into one- or two-year ranges. Overlapping dates double your numbers.

Most likely fix: Change the GA4 setting and retry

How to fix it

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

  1. 1. Change the GA4 setting and retry

    1. In Google Analytics go to Admin > Property Settings > User Analysis
    2. Turn off Enable user metric reporting
    3. Start a new import from Fathom site settings > More > Imports
    Did this fix it?

  2. 2. Split big imports

    1. Delete the failed import on the Imports page
    2. Run imports for one or two years at a time, one after another
    Did this fix it?

  3. 3. Fix doubled data

    1. Delete the import (native Fathom data is kept)
    2. Re-import with a range that ends the day before Fathom was installed
    3. Or untick Show imported data in the dashboard Options menu
    Did this fix it?

  4. 4. Wait or contact support

    1. Allow up to 48 hours; Fathom emails you when it finishes or fails
    2. For small imports that keep failing, retry later, then email support with the destination Site ID

Symptoms

Import email says it failed, the import sits in progress, or numbers roughly double after importing.

Why it happens

  • GA4 user metric reporting setting interfering with the import
  • Very large timeframe (millions of pageviews) timing out
  • Temporary Google API issues or rate limits
  • Import range overlapping dates Fathom was already tracking, or the same range imported twice
