iptables: Loading additional modules: ip_conntrack_tftp [FAILED]

I didn't find any solutions for Centos7. For Centos prior to 7 it seems to work without problems. lsof etc. doesn't exit for Centos7.

Tftp server works, but there are some problems accessing it through firewalls.

What can I do ?

It's solved. the ip_conntrack_tftp module was not compiled for my kernel version. After doing this, iptables loads without errors.
