Hi...

When try to open VM Console I got this:

Connection Error

For self-signed certificates:

Open this link in a new tab:
https://192.168.122.198:444/
Accept the certificate in your browser
Come back and try again

If I click Accept Certificate, I got it:

https://:444
Failed to open a WebSocket connection: invalid Connection header: keep-alive.

You cannot access a WebSocket server directly with a browser. You need a WebSocket client.

If I click open in Proxmox or External, I got this:

https://undefined:8006/?console=qemu&novnc=1&vmid=101&node=proxmox01

Thanks

Oh! Never mind.... After some minutes, console appears.

But the External link still leads to https://undefined:8006/?console=qemu&novnc=1&vmid=101&node=proxmox01

Thanks.

I'm sorry to reopen this thread, but it's seems something wrong still happens.
When click in external, is calling the correct IP from my Proxmox VE, however it's showing this:

Do I need to do something in PVE side?

Thanks

Hi @gilbertoferreira ,

Unfortunately, this is a Proxmox-side issue that we can't fix – we're just using their API.
Currently, we use a session code for this, which unfortunately doesn't work with the external view.
Regards,
Marcus
