Starting ProFTPD in Webmin displays an error

Hey, when I try to start ProFTPD in webmin it displays the following message:

Job for proftpd.service failed because the control process exited with error code. See “systemctl status proftpd.service” and “journalctl -xe” for details..

When i enter systemctl status proftpd.service i get the following:
proftpd.service - ProFTPD FTP Server
Loaded: loaded (/usr/lib/systemd/system/proftpd.service; enabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Wed 2019-12-11 12:57:45 EET; 15min ago

And when I enter the file and navigate to the line 356 and surrounding I see this info:

Perhaps you can help me.
