Description of problem:
If I disconnect from internet I can't reconnect until I reboot the system
SELinux is preventing dhclient from 'map' accesses on the file /var/lib/NetworkManager/dhclient-f7751877-018c-4740-9ab0-7fdd76d9e1f2-wlp1s0.lease.

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

If si crede che dhclient dovrebbe avere possibilità di accesso map sui dhclient-f7751877-018c-4740-9ab0-7fdd76d9e1f2-wlp1s0.lease file in modo predefinito.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
allow this access for now by executing:
# ausearch -c 'dhclient' --raw | audit2allow -M my-dhclient
# semodule -X 300 -i my-dhclient.pp
