After upgrade to Centos 7.7 (from 7.6), firewalld does not work anymore.
I have this in the firewalld log
Code: Select all
2019-09-20 15:46:27 ERROR: Failed to load nf_conntrack module: modprobe: ERROR: could not find module by name='nf_conntrack'
modprobe: ERROR: could not insert 'nf_conntrack': Function not implemented
modprobe: ERROR: Error running install command for nf_conntrack
modprobe: ERROR: could not insert 'nf_conntrack': Operation not permitted
All was ok before upgrade.
Any idea?
Thank you
Giuseppe
