03/29/2026, 12:23 PMFailed to obtain or add access token errors in your logs indicate that the replication-orchestrator is unable to authenticate internally â this is a platform-level authentication issue, not a source/destination connector issue.
Based on a similar case reported in the knowledge sources [token error issue], this error (Failed to obtain or add access token) appears during long-running syncs and can cause the sync to ultimately fail.
A related issue [deploy issue] points to a known root cause: the airbyte-auth-secrets Kubernetes secret not being properly created or managed. Specifically, one user noted:
> "It seems that the main problem here is to have the secret airbyte-auth-secrets pre-created. [...] having the secret pre-created and managed externally, the secret was not being updated even though I have configured the role to do so."
Recommended steps:
1. Check your Airbyte version â Several token-related issues were fixed in newer releases. Upgrading to the latest stable version is generally recommended [deploy issue].
2. If you're on Kubernetes, verify that the airbyte-auth-secrets secret exists and is correctly populated with valid dataplane client credentials. Ensure it is not being externally managed in a way that prevents Airbyte from updating it.
3. Check the timing â Your logs show the sync started on 2026-03-27 but the token errors only appear on 2026-03-29, roughly 2 days later. This suggests the sync ran for a long time before the token expired or became unreachable, which is consistent with the pattern seen in long-running syncs [token error issue].
The knowledge sources do not provide a definitive fix beyond the above. If the issue persists, consider reaching out via the Airbyte Community Slack or opening a support ticket if you're an Airbyte Cloud customer. đ 0 button đ 0 button âšī¸ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
