Followup:
I gave up on the Implicit and configured vsftpd for Explicit, that revealed some configuration errors (displayed on the client, Filezilla in my case). I then corrected these errors and switched back to Implicit and all is well.

Here's what I'm using. The tutorial site I used is currently down with a bandwidth exceeded warning, so I guess it must be quite popular.
I'm using LetsEncrypt certificates. My site domain is replaced with example.com. Use your own domain name there as registered with LetsEncrypt.
