Azure Virtual Desktop: Display Issues in a Session — Troubleshooting Endpoint Reachability Failures

문제 설명

I am experiencing display issues when using Azure Virtual Desktop, specifically after updating my Windows App client from version v2.0.1315.0 to v2.0.1375.0. The Endpoint Reachability check fails for multiple Microsoft endpoints, resulting in NetworkError and WinHttpOpen failed errors. Although I can access the cloud resources, the connection diagnostics indicate problems with reaching specific endpoints.

환경

Azure Virtual Desktop service; Windows App client; region not specified in case information.

이미 시도한 내용

I have compared logs before and after the update, verified network connectivity to Microsoft endpoints, and checked proxy configurations. I also confirmed that direct access to cloud resources is possible despite the Endpoint Reachability failures.

현재 상태

I am seeking guidance on the possible causes of these reachability failures post-update, particularly whether changes in proxy or WinHTTP handling might be involved, and what troubleshooting steps I can take to resolve these display and connectivity issues.
