The other person deleted their comment to you about Hetzner accounts being randomly terminated before I could reply, so I'll send my reply here:
This happened to me when I tried to sign up for Hetzner on a whim in June. I'd heard they have ARM offerings and wanted to try them out, so I got through the account registration process and set up a machine. I'm not exactly sure what I did wrong – I think I was trying to change my primary email address, or maybe set up billing – but I was promptly logged out and my account was deleted. They sent me the following automated email:
> Dear Joshua Harms
> After reviewing your updated customer information, we have decided to deactivate your account because of some concerns we have regarding this information. Therefore, we have cancelled all your existing products and orders with us.
> Best regards

I suspected it was because I was using Apple's Private Relay VPN while creating the account, so I turned that off and signed up again with a different username/email address. No issues with the new account so far, but I continue to hear about other people having their accounts terminated.
I haven't moved anything serious over to Hetzner yet, but to be fair I wasn't intending to unless their ARM CPUs become available on private instances.
