r - HTTP/1.1 503 Service Unavailable -

i using boxr package csv files box.com website. have done authentication , able access files in account.

httr::set_config( config( ssl_verifypeer = 0l ) ) library(boxr) box_auth() as.data.frame(box_ls(dir_id = box_getwd())) 

till here, works fine , able file_id's , folder contents

but when use box_read/box_dl commands read/download file gives following error:

box_dl('156269543760') |===========================================================================================================| 100% error in boxget(file_id = file_id, version_id = version_id, version_no = version_no,  :  error downloading file id 156269543760: server error: (503) service unavailable 

i have varied size of file (csv) read form 15kb's 40 mb. have read somewhere may due server being busy, after trying multiple times in 2 days, still getting same error.

is there wayaround this? appreciated.
