EOS User Permission not working

Hey there folks,

I’m integrating EOS in UE5.6 and running into a login issue with test accounts.

  • Login method: EIK_LCT_Developer (UseEas = true, ExternalAuth = EIK_ECT_EPIC)

  • The request reaches EOS, but fails with:

ErrorCode: errors.com.epicgames.oauth.corrective_action_required
HttpStatus: 400

  • The continuation URL is returned, but the overlay never appears. In the logs I see:
    “Account Portal overlay failed to load … falling back to browser flow”

  • When I manually open the continuation URL in a browser, nothing changes.

  • The test accounts are added to the correct player group and have access to the Live sandbox my client is pointing to.

  • I already accepted Terms of Service and Privacy Policy on the Epic Games website for these accounts, but the login still fails.

Question:
Has anyone seen this before? Is there something else I need to enable in the Developer Portal or in the test account settings so the corrective action can be resolved? This was not like this 3 years ago

Thanks in advance!
