Step 1: Check network connection

To ensure the network connection is stable, you can suggest the user open another web page or application to confirm that the network is working properly, or try another trusted network connection to confirm whether the issue is related to a specific network.

Step 2: Check firewall and network settings

Please ensure that the user's firewall or network settings do not block related ports or services.
