Hello Sakari,
thanks for your posting.
We have checked your account and it's fully active. It seems this is affecting some of our users in Finland. mailbox is not blocking connections from Finland. This appears to be a DNS or network-related issue rather than an issue with your mailbox account.
Could you please check what you are seeing when you click this: https://check-host.cc/http?host=https://app.mailbox.org®ion[]=FI (Check-host.cc is an online network diagnostic tool that tests website availability, server response times, and IP routing from multiple global locations.)
If the problem is related to your network connection, please test with a different internet connection, such as a LAN connection or a mobile hotspot.
We recommend contacting your Internet Service Provider (ISP) or network administrator so they can check the DNS resolution and network connection to our mail servers.
Kind regards
Your mailbox Team

As a stopgap measure, you can try using a custom DNS resolver and see if that helps: https://userforum-en.mailbox.org/topic/5556-current-issues-with-login-and-sendingreceiving-emails#comment-14716
