RESOLVED 2 months ago - at 04/20/2026 08:23AM

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.
