Creating ARM instances not possible

[niklaszulus]

When trying to create an ARM instance i get following error

ERROR: Error creating machine: Error in driver during machine creation: could not create server: missing image

When using x86 based images everything works fine

To reproduce try creating a server using either cli or in my case autoscaling Gitlab Runnners

"hetzner-api-token=************", 
"hetzner-image=ubuntu-24.04", 
"hetzner-server-type=cax21", 
"hetzner-server-location=nbg1"

Leads to ERROR: Error creating machine: Error in driver during machine creation: could not create server: missing image

"hetzner-server-type=cx22" This works

I also tried specifying the image id from the API e.g. 161547270 (Ubuntu 24.04 on arm) which leads to this error

ERROR: Error creating machine: Error in driver during machine creation: could not create server: image has incompatible architecture (invalid_input)

For context: Im running an autoscaling server for Gitlab runners. The "broker" (The server that autoscales the other servers) runs on x86

Same here. All ARM instances fail to init.
