AVD connection paused or disconnecting

Question

We have a AVD environment, and recently when remote to systems via Windows App. We are get disconnected , network paused, virtual disk, FSlogix errors. The session do not seem stable. The logs from the VM are stating there is a DNS issue, but we Do not control DNS for Azure. I have this issue in the office and from home. Has any one had the Network pause errors or dropping of connection sessions ?

Answer 1

@Tennant, Andrew welcome to the Microsoft Q&A community.

Below are a few key areas to investigate.

1. DNS Configuration

Even if you don’t manage Azure DNS directly, misconfigured or unreachable DNS endpoints can cause session drops. Consider:

Verifying that your session hosts can resolve internal and external names consistently.

Using Azure-provided DNS or explicitly setting custom DNS servers in your virtual network settings.

2. FSLogix Profile Container Issues

FSLogix can be sensitive to:

Storage latency or permissions misconfigurations on the profile share.

Antivirus interference—make sure FSLogix paths and VHD locations are excluded.

Cloud Cache misbehavior—if enabled, it can cause profile mounting delays or failures.

3. Session Host Health

Check:

VM performance metrics (CPU, disk I/O, network throughput).

Event Viewer logs under Applications and Services Logs > FSLogix for profile load errors.

The frxtray tool on session hosts—it gives a quick status of FSLogix profile health.

4. Network Stability

Since the issue occurs both at home and in the office, it might be:

A backend Azure networking issue (e.g., virtual network peering, NSG rules).

• Or Windows App client instability—try updating or switching to the web client temporarily to compare behavior.
