Access ZVM virtual machines remotely?

Running latest Zima 1.3.0-2…

I’ve setup remote access to my Zima instance, via a cloudflare tunnel. Works great, but ZVM virtual machines display. I can open ZVM from dashboard, and click to start a machine, but the display never loads (just shows “…” flashing). The VM does start though - if you log back in direct via local network IP rahter than via tunnel, I can see the VM fine and it is running)

Any ideas?

(I can’t rely on tailscale/twingate/zerotier as they are all blocked on my work network)
