Description Stephen Victor 2017-11-10 13:31:57 UTC
Description of problem:
I simply restarted, and the error appeared.
SELinux is preventing nm-dhcp-helper from 'connectto' accesses on the unix_stream_socket /run/NetworkManager/private-dhcp.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that nm-dhcp-helper should be allowed connectto access on the private-dhcp unix_stream_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'nm-dhcp-helper' --raw | audit2allow -M my-nmdhcphelper
# semodule -X 300 -i my-nmdhcphelper.pp
