Hello,
I've been trying to use wget to download MERRA data from this link:
https://goldsmr4.gesdisc.eosdis.nasa.gov/opendap/MERRA2_MONTHLY/M2TMNXFLX.5.12.4/1991/MERRA2_100.tavgM_2d_flx_Nx.199101.nc4.nc4?SPEED[0:0][0:60][0:575],time,lat[0:60],lon[0:575].
But i keep getting this error: Unable to establish SSL connection. I tried downloading with python "requests" and "pydap" but I get the 401 Unauthorized Error and webob.exc.HTTPError: 404 Not Found, respectively.

(the reason why i don't download it directly from the URL is that i have a .txt with +100 urls to download and I'm trying to download one as a test, I've tried with other URL's but i get the same errors)

Here's my code
C:\>wget --load-cookies C:\.urs_cookies --save-cookies C:\.urs_cookies --auth-no-challenge=on --keep-session-cookies --user=paunaranjo --ask-password https://goldsmr4.gesdisc.eosdis.nasa.gov/opendap/MERRA2_MONTHLY/M2TMNXFLX.5.12.4/1991/MERRA2_100.tavgM_2d_flx_Nx.199101.nc4.nc4?SPEED[0:0][0:60][0:575],time,lat[0:60],lon[0:575]
