Clearhaus Outage History

Between 2026-08-27T00:30:35Z and 2026-08-27T00:48:01Z, all Visa authorizations failed with status code 40400, "backend problem". A few Visa transactions were failing already starting 2026-08-27T00:25:25Z. Mastercard authorizations along with all captures, refunds, voids and credits were unaffected. We have seen no further connectivity errors since 2026-08-27T00:48:01Z. Failed authorizations were not charged and can be retried. We are working with our upstream provider to determine the root cause and to prevent similar issues in the future.

Since 2026-08-12 00:05 CEST, approval rate of Mastercard Credits are back to normal. We are still working with the upstream provider to investigate the core issue, and ensure continued operations. Regular authorizations and all other transaction types remain unaffected.

This incident has been resolved.

The /settlements endpoint in Merchant API was unavailable and returning 500 between 2026-02-03T08:55Z - 2026-02-03T09:15Z. The incident was resolved with no lingering issues.

We are closing this incident as no error has been observed since 9:23 UTC and since our upstream provider confirms that service has been restored. An average failure rate of 8.98 % was observed between 07:48:49 UTC and 09:23:30 UTC (of when the first and last error occurred). Authorizations and voids were affected. Captures, capture refunds, debits and debit refunds were unaffected. Mastercard credits were affected. Visa credits were unaffected.

After taking remedial action, performance of the degraded components has returned to normal during the course of the week. Additionally, we have taken measures to improve visibility into the affected systems in order to strengthen our infrastructure and prevent similar events in the future. We are in contact with the service provider to continue to investigate the root cause of the issue and explore additional measures to increase the robustness of our systems.
