2026-February-23 Service Incident
Incident
Report for Sauce Labs
Postmortem
Dates:
Monday, February 23rd 2026, 17:22 UTC - 22:31 UTC
What happened:
WDIO-based tests run by customers using Sauce Connect 4 could not be started.
Why it happened:
Misconfiguration caused failing health checks in some cases, causing customer tunnels to shut down.
How we fixed it:
Misconfiguration was corrected.
What we are doing to prevent it from happening again:
Evaluation of the underlying software stack.
Customers who are still using SC4 that can migrate to SC5 should do so at their earliest convenience.
Resolved
We have identified the root cause and deployed a fix for this issue. All services are fully operational.
Update
We have identified the root cause and are working on implementing a fix. We are continuing to investigate.
Investigating
We are seeing an increase in automated tests using Sauce Connect failing with “Misconfigured -- No active tunnel found for provided identifier” errors in the US-West-1 data center. We are actively investigating.
This incident affected: Automated Browser Testing (US-West), Automated Virtual Mobile Device Testing (US-West), Automated Real Device Testing (US-West), and Sauce Connect (US-West).
