Hi Rami,
/etc/resolv.conf before NM restart
----------------------------------
# Generated by NetworkManager
nameserver 192.168.100.1
/etc/resolv.conf after NM restart
----------------------------------
# Generated by NetworkManager
journalctl -f before and after NM restart: See attached file
"journalctl-f" (the dashed line in "journalctl-f" marks the restart)
Kind regards
