Can't load custom map on rust server Logs + Config included

Hello all! I have been trying without success to load the Gravis map as a custom map on my rust server. Any help would be greatly appreciated. 

My config:

echo off
:start

cd rustds
RustDedicated.exe -batchmode +server.hostname "Yazzur" +server.port 28015 +server.identity "my_server" +server.levelurl "https://raw.githubusercontent.com/Ryan-J-D/Rustoria.Maps/master/GravisIslandv1.5.1.map" -logFile "output.txt" 
cd ../

goto start​


Rust server log:

This is also a problem I am facing, please let me know if you find a fix :D
