Unable to download DEM file with dem.py

[tryingphysics000]

Hi Everyone,

I am trying to download DEM file for running stripmapApp.py with dem.py with the following command:

!dem.py -a download -b 22 23 72 73 -r -c
But I got the following error:
curl -n -L -c $HOME/.earthdatacookie -b $HOME/.earthdatacookie -k -f -O http://e4ftl01.cr.usgs.gov/MEASURES/SRTMGL1.003/2000.02.11/N22E072.SRTMGL1.hgt.zip

N22E072.SRTMGL1.hgt.zip = failed
However, when I am opening the url http://e4ftl01.cr.usgs.gov in the same system, it is working. But it is not working using dem.py.
Thank you in advance for any insights or assistance you can provide.

Regards,

Hi everyone,

I am having trouble with the verifyDEM step in stripmapApp.py. I'm encountering the following error:

Running step verifyDEM

However, if I specify an external DEM download from Earthdata, I encounter another error: "no file found N22E072.hgt.xml" where the specified DEM is N22E072.hgt.

Is there any way to specify external dem into stripmapApp workflow?
