Transfer a Docker-HA Backup to new VMWare HAS

Hi at all,
im new in this topic.
I startet a few weeks ago, with a small project. Set a max-Power for a Wallbox with PV.
I took a docker and started it. What a nice Thing!!! So it grows and grows. Now i want use addons and Hacs, so i have to hop on a supervised-Version.
I took the vmware-ova Image and run it on a Synology Virtual Machine Manager. Everything is fine!

But now, i want to restore my backup from the Docker-HA on the new vmware-HAS.
i create a new Backup and select it with the new installation. I get no feedback and the connection to the frontend broke down.
Is there a chance to port my old things to the new one? Some Workaround? I hope so!

Best Regards Paul

The problem is solved!
I used in my Docker-HA https, so i have to connect on my new VMWare-HA with https, also.

Maybe you can delete this topic.
