Error in R_nc4_open

Hi,
error-Error in R_nc4_open: NetCDF: DAP server error
Based upon the error above, the issue appears to be on the server side not your client end.  Perhaps the URL to the grib file is not correct?  I know that I recently switch NOMADS related URLS from http to https.

You also asked about mailing lists.  If you are working with geospatial data then you might like the r-sig-geo list here https://stat.ethz.ch/mailman/listinfo/r-sig-geo

Hi Jeff,
Thanks for your detail response but I am really baffled by this sort of
response from a help group because I am also a part of a help group
(NCAR-Command Language).

Anyway I felt its R/Rstudio issue because my code was working properly
before..........but since the update it isn't working anymore

Here is few lines of my code

library("ncdf4")
gribfile<-"
http://nomads.ncdc.noaa.gov/thredds/dodsC/modeldata/cfsv2_forecast_ts_9mon/2011/201104/20110401/2011040100/tmax.01.2011040100.daily.grb2
"
## open connection
nc <- nc_open(gribfile)

error-Error in R_nc4_open: NetCDF: DAP server error

I am getting the error message in nc_open.

Please excuse me if this not R issue. Please let me know which "*R HELP
GROUP*" I should post this message.

You will do yourself a favor if you pay attention to which software you
are using.  When you use RStudio, the console window is a direct connection
to R, which is NOT RStudio... it has a separate installer and a different
support group (e.g. this mailing list). All of this means you have failed
to tell us anything about the software that actually matters in your
question... R, nor the CONTRIBUTED package (meaning NOT part of R or
RStudio) containing the function you are having trouble with.

Go read the Posting Guide... carefully... and provide a reproducible
example that leads to your error... and post in plain text rather than HTML
email so your example doesn't get messed up in transit. The output of
sessionInfo() after the error would probably be a good idea also. For good
measure you should open R directly rather than through RStudio and confirm
the results (if it doesn't happen in R then RStudio may be breaking R
(rare, but it has happened) in which case you would have to ask them for
help.
