I was refused renewing the domain or moving to a different registrar. Given that I was unable to get a satisfying answer and the old domain was due to expire, I went ahead and bought the new domain danwin1210.de, to switch over to. danwin1210.me went down after expiry, but thankfully I was allowed to pay for extension by creating a new account and depositing the money for renewal there, so it was back up shortly...
