We are seeing an elevated error rate for some customers for POST requests. This appears to be limited to a small subset of organizations using custom domains for hosted Authkit
- resolved Sep 09, 2026, 11:02 PM UTC
We have identified the source of the problem. A configuration change that applied to roughly 2% of organizations using a custom domain for hosted Authkit resulted in form submission errors. The configuration has been reverted and service restored.
