Hi 

When i want to use getGEO function to download GSE dataset with this code:

series <- "GSE85358"
gset <- getGEO(series , GSEMatrix =TRUE, AnnotGPL=TRUE, destdir = "....." )

,i encounter this error:

https://ftp.ncbi.nlm.nih.gov/geo/series/GSE2nnn/GSE2553/matrix/
Error in function (type, msg, asError = TRUE)  : 
  error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

how can i fix it?

thanks
