   We are currently investigating reports of resolution issues affecting some users who have updated to our latest version or are deploying the new version of our DNS Client, specifically when attempting to access certain sites that were previously blocked. Our team is actively working on a solution to ensure uninterrupted access for all users

2. resolved Apr 20, 2026, 08:23 AM UTC

   We identified an issue affecting some users running the latest version of our DNS Client when accessing certain sites that were previously blocked. This behavior was linked to recent changes in upstream load balancing behavior during the handling of HTTP/2 to HTTP/1.1 traffic, including differences in how headers and compression are processed and forwarded between services. The agent now operates with both formats and compression strategies in our load balancer and edge environments. With this update, resolution behavior has been restored and access should now be functioning as expected.
