Proxmox SPICE access not working after node change

[René Pfeiffer]

Hello!
I run a Proxmox cluster of three nodes. One of the nodes was replace by new hardware. Four of the VMs run desktop systems that are accessed by SPICE (via the SPICE shell scripts from Proxmox). The SPICE access doesn't work any more (only for one of the systems). The web console also reloads and does not display the screen. I tried "pvecm updatecerts" and checked the cluster connection. The logs only show lines like this:

Jan 08 10:01:41 node2 spiceproxy[3158932]: problem with client ::ffff:x.y.z.200; Connection reset by peer

The remote-viewer does not show any errors on the client side. Where do I look for the error?

Best regards,
René.

I already tried to update the node certificates via "pvecm updatecerts -F ; systemctl restart pvedaemon pveproxy" and restarted the VMs. No change.
