Task name

PublishTestResults@2

Task version

2.270.0

Issue Description

The task typically runs within a few seconds. As of 2026-04-15 10am EST, the task hangs for a long time (10-15) minutes. It eventually logs a RemoteCertificateNameMismatch exception, but ultimately ends up succeeding.

This is causing our pipeline runs to take an extraordinary amount of time.

This is happening on an Azure Managed DevOps Pool (quasi-self hosted) runner.
