UTM Remote on iPad setup seems fine but can't run any VM

[crutch68k]

Describe the issue
I have UTM Remote on my iPad running UTM Server on macOS. The VMs (vintage Mac Quadra 800s running System 7 flavors) run fine on UTM Server locally but, when I try to run them remotely via UTM Remote (downloaded from the App Store) on my iPad, I get a spinning circle for 10+ minutes and finally a network error. UTM Server on macOS sees the iPad connected but the UTM app on macOS also shows the eternal spinning circle in the particular VM, see image. After a very long time I get an error on the iPad, "The operation couldn't be completed (Network.NEWError error 53 - Software caused connection abort)"

I already ensured UTM, QEMUHelper, QEMULauncher have fill disk access in macOS.

Configuration

• UTM Version: Version 4.6.4 (107)
• macOS Version: 15.0
• Mac Chip (Intel, M1, ...): M1

Debug log
Attached. There is never an actual crash but I pulled the debug log after waiting a few minutes watching the spinning circle ....

Upload VM
Uploaded one of my VMs here as an example, but this happens with all of them.
