You store u/p to your Lawyer's website, which has a copy of your Will. You die and the Executor of your Estate tries to access the Lawyer's website, only to be met with "invalid password".
It turns out that the kdbx on your private server got silently corrupted (ex. fs corruption) ~5 years prior to your death. However, your Dropbox backups only have 30 days of previous kdbx versions.
1) Random port is not helping against a specific attacker. Get a real firewall
2) Fail2ban is not a real firewall
3) Keys only, no passwords. 40chars is nothing compared to a strong rsa key with a 40char password on it

Can your Executor handle the disappointment?
I believe this issue is grave enough.
