Hi Lei,

Are you using a web browser from Windows OS? It seems that there is an
issue of Windows websockify/novnc. Use a browser from OS other than
Windows til the issue is resolved.

Did you test it using Tight VNC viewer after enabling external
connection? The reason why I suggested that is to identify whether
this issue comes from KVM web proxy or from KVM server.

Need more information of your test environment.
Server platform:
BMC SoC:
Host OS:

Regards,
Jae
