vsftpd centos 6.7?

I havent set up an ftp server in years, i got the ssl cert working but in filezilla its buggy as hell, if i enter details on the quick connect line it will give either a gnu utils error 15, or a econnabort. if i use site manager set it to ftp and ftp use tls it logs in fine
and ive forgotten how to set it up properly, i tried google and the config file uses pasv etc any ideas please?

It also for some reason skips the welcome banner. (and yes i uncommented it lol, in plain it shows fine)

A simple reboot solves the issue, but it comes back randomly, restarting the server makes no difference

edit that update 2, i mean rebooting vsftpd makes no difference but restarting the entire server fixes it and all works well for a time.
