Hello Marc and Corey, This really helped a lot! I have added to /lib/systemd/system/ser2net.service
After=network-online.target Wants=network-online.target ad below and rebooted the pi and upon restart ser2net started successfully! ``` [Unit] Description=Serial port to network proxy Documentation=man:ser2net(8) After=network-online.target Wants=network-online.target [Service] EnvironmentFile=-/etc/default/ser2net ExecStart=/usr/sbin/ser2net -n -c $CONFFILE -P /run/ser2net.pid Type=exec Restart=on-failure [Install] WantedBy=multi-user.target ``` Thank you a lot!!!
