With two 26.7.1_1 test VMs that I set up on Proxmox 9.2.4, tailscale is working normally. However, on the Interfaces/Assignments page, the status icon for the tailscale interface is red.

Yet, on the Interfaces/Overview page, the status icon for the tailscale interface is green.

Again, tailscale seems to be working normally, so I think the issue is cosmetic.
