[idvusers] accessing NASA MERRA-2 via URL

Hello,
I am having trouble accessing MERRA-2 data from their opendap URL located below:
https://goldsmr4.gesdisc.eosdis.nasa.gov/opendap/MERRA2_MONTHLY/M2TMNXSLV.5.12.4/1980/MERRA2_100.tavgM_2d_slv_Nx.198001.nc4.html
 Does anybody have an idea on how to use the "Data URL" to load the data into 
IDV?

In the past with other datasets, I substitute https with dods and everything 
works well. However, in the case above, I am unable to access the data via URL. 
Has anybody had success in accessing the MERRA-2 data from 
here:https://disc.sci.gsfc.nasa.gov/uui/datasets?keywords=%22MERRA-2%22

Thank you for your insights.Sincerely,teddy allen
