Why is the QuWAN Agent UI stuck on the Loading screen?


Last modified date: 2026-03-11

Description

When opening QuWAN Agent on the NAS, the UI may remain stuck on the Loading screen and the installation process cannot proceed.

Cause

This issue may occur when Port Trunking is enabled in the NAS network settings. When a network adapter is configured with Port Trunking, QuWAN Agent may not be able to properly initialize the network environment, causing the UI to remain on the Loading screen.

Solution

Please check the NAS network settings by following these steps:

  1. Log in to the NAS management interface.

  2. Go to Network & Virtual Switch (NVS).

  3. Check whether Port Trunking is configured on the network adapters.

  4. If Port Trunking is enabled, remove or disable the configuration.

  5. Reopen QuWAN Agent.

After removing the Port Trunking configuration, QuWAN Agent should be able to launch normally and proceed with the setup process.
