SELinux is preventing /usr/sbin/httpd from name_bind access on the tcp_socket port 85.
***** Plugin bind_ports (99.5 confidence) suggests ************************
If you want to allow /usr/sbin/httpd to bind to network port 85
Then you need to modify the port type.
Do
# semanage port -a -t PORT_TYPE -p tcp 85
where PORT_TYPE is one of the following: http_cache_port_t, http_port_t, jboss_management_port_t, jboss_messaging_port_t, ntop_port_t, puppet_port_t.
***** Plugin catchall (1.49 confidence) suggests **************************
If you believe that httpd should be allowed name_bind access on the port 85 tcp_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 'httpd' --raw | audit2allow -M my-httpd
# semodule -X 300 -i my-httpd.pp
