service exits after ssh disconnect

The service works perfectely if I am not logged in, but if I connect with ssh and then disconnect the service gets terminated. The service belongs to the user to whom I ssh. This is my current ts3.service file: [Unit] Description=TeamSpeak3Server [Service] User=user1 Group=staff Type=forking WorkingDirectory=/usr/local/bin/teamspeak3-server_linux_amd64 ExecStart=/usr/local/bin/teamspeak3-server_linux_amd64/ts3server_startscript.sh start ExecStop=/usr/local/bin/teamspeak3-server_linux_amd64/ts3server_startscript.sh stop PIDFile=/usr/local/bin/teamspeak3-server_linux_amd64/ts3server.pid RestartSec=5 Restart=always RemainAfterExit=yes [Install] WantedBy=multi-user.target I have already tried changeing ExecStart to ExecStart=/usr/bin/nohup /usr/local/bin/teamspeak3-server_linux_amd64/ts3server_startscript.sh start Other services like openvpn survive the ssh logout. After reconnection the status of the systemd process reads: active (exited) while the normal status is active (running) Could the cause of the problem be that the script which I execute calls another script which gets killed if the shell sends sighup meassages? Thank you for your answers. **Edit:** the important part of ts3server_startscript.sh are as follows: COMMANDLINE_PARAMETERS="${2}" D1=$(readlink -f "$0") BINARYPATH="$(dirname "${D1}")" cd "${BINARYPATH}" LIBRARYPATH="$(pwd)" BINARYNAME="ts3server" if [ -e "$BINARYNAME" ]; then if[ -x "$BINARYNAME" ]; then export LD_LIBRARY_PATH="${LIBRARYPATH}:${LD_LIBARY_PATH}" "./${BINARYNAME}" ${COMMANDLINE_PARAMETERS} > /dev/null & PID=$! ps -p ${PID} > /dev/null 2>&1 if [ "$?" -ne "0" ]; then echo "..." else echo $PID > ts3server.pid fi So if I interpret that correctely the server is started in the console by "./${BINARYNAME}" ${COMMANDLINE_PARAMETERS} > /dev/null &
