DenyUser Limit does not work for ftp, but works for sftp about proftpd

Could you provide the ProFTPD debug logging, debug level 10, for both the FTP and SFTP logins for the user in question? I'm hoping that that logging can help provide more details about what is happening. Thanks!

Here are the logs with the config above. If you need more from the config, i can provide it.

Hmm. In the provided logs, it looks like you are using an SFTP client in both cases to log into your two separate <VirtualHost> sections. That's not what I expected. I thought you would use an FTP client for the FTP virtual host, and an SFTP client for the SFTP virtual host. FTP and SFTP are very, very different protocols.

Tried again. Now i have two new findings:

1. I dont see logs from the ftp virtual host. I dont know, why logins and other things are not logged.
2. If i try ftp localhost, then the Limit restrictions do not apply. They do apply when i ftp to the outbound IP of the server. But the proftpd process listens on 0.0.0.0:21 - no other process or xinetd picks up connections to 127.0.0.1:21

Found out, that this is a configuration issue, where ftp clients sometimes do not land in one of the VirtualHost contexts, but in the "server config" section.
I added a
Port 0
to the outer server config, and now it works as expected.

Interesting. But I'm glad you were able to make it work!
