spice virt-viewer disconnected when unplugging laptop from dock and switching to WIFI network

[prolab]

I have installed virt-viewer 9.0 on a Windows laptop and use it to connect to virtual machines in a remote Proxmox VE server. I noticed when I unplugging the laptop from docking station (where it is connected through to LAN network cable), and switching to WIFI network, the virt-viewer window will disappear. I assume the virt-viewer can't reconnect when network get lost.

I downloaded the download.vv from Proxmox VE's web ui. I launch it using PowerShell. This is the log when network disconnected:

C:\Windows\system32>"C:\Program Files\VirtViewer v9.0-256\bin\remote-viewer.exe" "C:\Users\XXX\Downloads\download.vv"

I have asked at the spice-devel mailing list: https://lists.freedesktop.org/archives/spice-devel/2021-January/052113.html It's said that there are two cases:

1, the remote-viewer/virt-viewer is not making reconnect attempts.
2, the remote-viewer/virt-viewer is able to make reconnect attempts, but the token get expired.

What's the case? How to debug to find out which is the case?

I have used Windows RDP, that client's behaviour is it will attempt to reconnect for a few times. So I hope to have the similar feature.

2, the remote-viewer/virt-viewer is able to make reconnect attempts, but the token get expired.

True, I guess the token has expired, you need to do that as speedily as possible

"C:\Program Files\VirtViewer v9.0-256\bin\remote-viewer.exe" "C:\Users\XXX\Downloads\download.vv"

I assume the virt-viewer can't reconnect when network get lost.

the donaload.vv will be destroyed after use. And note, you only have 40 sec to connect with downlaod.vv after 40 sec the token will be expired [1]
