Create new account when restored Home Assistant

I have restored HomeAssistant to another NUC since the one Home Assistant was running on crashed. On my backup I have copied the .storage folder including the account information. For some reason this seems not to work. After restore I started Home Assistant and It was starting in onboarding mode asking for a new owner account setup. Ok fare enough, I entered account details and pressed the blue button ‘account aanmaken’ (because I use a Dutch version), but nothing happens.

Then I decided to do the account reset procedure as described on the site, by removing some auth files form the .storage folder. (I do this using a local network connection on http://192.168.0.26)
Again nothing happens when I press the button… What am I doing wrong, and why is my backup not simply working?

I don’t have the answer but maybe it’s more straightforward to use snapshots in your case?
