Service temporarily unavailable

[QuocPhamBao]

Hello,
I got the below error while trying to access the open data:
Error : Service temporarily unavailable
The server is temporarily unable to service your request, please try again later.
May I know is there any way to access or download the data in this situation ?

This is the code:

loginUDG(username = "", password = "")

data("PRUDENCEregions", package = "visualizeR")
bb <- PRUDENCEregions["FR"]@bbox
lonLim <- c(-5,9); latLim <- c(42,51)

grid.list <- lapply(var.list, function(x) {
loadGridData(dataset = "ECMWF_ERA-Interim-ESD",
var = x,
lonLim = lonLim,
latLim = latLim,
years = 1980:2008)
}
)
