vsftpd - sftp works fine, ftp freezes

Hello,

Recently I've set up vsftpd, everything's running fine, however I was asked to allow the ftp connections also, as I was informed that it wasn't working at all.
So I ftp'd to 127.0.0.1 and got:

Connected to 127.0.0.1 (127.0.0.1).

And it's sitting there, doing nothing. No 200, no nothing. I have to Ctrl+Z out of it. The process is getting created but that's it. I've created new users, changed paths, tried so many thing I lost count. I can't even diagnose what's happening, because nothing is being written to the logs (except for sftp.log, which is for sftp and doesn't help me in any way).

I've adjusted sebools (ftpd_use_nfs, ftpd_full_access, use_nfs_home_dirs) but then I've just switched it to permissive so I could narrow down what's the culprit, so SELinux can be taken out from the equation.

Xfer.log, vsftpd.log and sftp.log are all in the same path (nfs). Homedirs are on a separate nfs. Permissions are set so the jail would work properly. Socket for each user is created to get info about the connections.

Here are my configs:
