SITL is not working properly

I’m trying to run the sim_vehicle.py script but it cannot run because the script try to download the map from the internet (SRTM Download failed /SRTM/Australia/S38E143.hgt.zip on server firmware.ardupilot.org) and always fail. I thin there is nothing in /SRTM/, because I checked that on the internet, it has in /SRTM3/. However, this is set up in the script code. Is there a bug or something else?

Thanks in advance!

I am facing the same problem. Did you find any solution?

Try to disable that downloading option in parameter…i think terrain enable has to be 0 in this case
