Terrain data is not loaded


i try to use the terrain waypoint feature in arducopter.
terrain_enable 1
terrain_follow 1 (even if its not needed i think)

gps fix
mission planner connected and has internet connection (terr_pending 112)
“prearm waiting for terrrain data”

but nothing is loading. terr_load is not changing.

any advice or do i miss something? i tryed also older versions of mission planner. all the same.

thansk :slight_smile:

in mission planner, flight plan tab, were the SRTM should be there is an “invalid” … ?!
