use this start.bat. i fixed it so it wil work!.

@echo off
cls
echo Protecting srcds from crashes…
echo If you want to close srcds and this script, close the srcds window and type Y depending on your language followed by Enter.
title srcds.com Watchdog
:srcds
echo (%time%) srcds started.
start /wait srcds.exe -console -game garrysmod +gamemode sandbox +map gm_flatgrass +maxplayers 128 -tickrate 120 +port 27185
echo (%time%) WARNING: srcds closed or crashed, restarting.
goto srcds

sooo. its + port not -port… and this one works for me… you also have to remember to port forward. here is a youtube video that shows what to do it https://youtu.be/v7zlPbHKHbY . remember you are using the port 27185 so you have to use that port. then use this server config that ill make for you.

hostname “Test”
//change the rcon password
rcon_password “myrcon”
//SandBox Settings
