Hello Jason Pak,
Thanks for posting your question in the Microsoft Q&A forum.
This is a complex issue that could have multiple causes.
- If you're using a VPN, ensure it's configured correctly and not causing conflicts with the AVD connection.
- Temporarily disable any third-party firewall or security software to see if it's interfering with the connection.
- Try connecting via the AVD web client to see if the issue persists, which could help isolate whether it's a client-specific problem.
- If possible, test the connection from a different network to rule out local network issues.
- Ensure you're using the latest version of the Microsoft Remote Desktop client for Mac. Sometimes, older versions can have compatibility issues.
