<Error in curl::curl_fetch_disk(url, x$path, handle = handle): Timeout was reached: Connection timed out after 10000 milliseconds> R Package SLGA

I'm trying to use the SLGA package to find the sand content of soils in Australia.

I am behind a firewall at work and so previously could not install the package from github, but now can download from the CRAN repository.

Unfortunately though, I am unable to use the functions to call data possibly because of the firewall.

I tried to use some example functions from github and another question on here and get the timeout for all of them.

Looking at other similar questions looks like it's a proxy/firewall/DNS issue but I'm not really sure what to do as I don't have admin privileges on my machine.

I may be able to request through my IT team that the required URLs are not blocked but I'm not sure exactly which I should ask for-

http://www.clw.csiro.au/aclep/soilandlandscapegrid/ or http://www.asris.csiro.au/arcgis/rest/services/TERN or others?

Any ideas how I can do this @obrl_soil?

aoi <- c(152.95, -27.55, 153.07, -27.45)

bne_surface_clay <- get_soils_data(product = 'NAT', attribute = 'CLY', 
                                   component = 'ALL', depth = 1, aoi = aoi,
                                   write_out = FALSE)

Error:

Error in curl::curl_fetch_disk(url, x$path, handle = handle) : Timeout was reached: Connection timed out after 10015 milliseconds

Solution

I've seen similar issues at my workplace. A proxy is often the issue and a common solution is to add appropriate environment variables.

For example if the proxy URL is proxy.abc.xyz on port 80, you can define:

HTTP_PROXY=proxy.abc.xyz:80
HTTPS_PROXY=proxy.abc.xyz:80

This can be in a .Renviron file. Or on Windows 10, you can open "edit the system environment variables" in Control Panel.
