[BioC] Error in getGEO command with GSEMatrix=TRUE

[Marwaha, Shruti (marwahsi)]

Dear Developers,

I am trying to  get an ExpressionSet from a GSEfile using getGEO command with GSEMatrix=TRUE. It sometimes gives an error (Connection was reset) if I use GSEMatrix=TRUE however sometimes it works smooth. I have the latest version of R, Bioconductor and GEOquery. Please advise if I am missing some library or need to change some settings. Thanks in advance.

My Code
library(Biobase)
library(GEOquery)
library(limma)
gset <- getGEO("GSE27347", GSEMatrix =TRUE)

Error:
Error in function (type, msg, asError = TRUE)  :
  Send failure: Connection was reset

Methods already attempted

*         I have tried it on both RStudio and GUI

*         I have also tried using the command "setInternet2(use=FALSE)" but it doesn't help.

*         I have tried this command with other GSEfiles also and get the same error.

*         GEOquery works fine and downloads the GSEfiles if I give GSEMatrix=FALSE

*         I have also tried downloading the file and provide the file path of the file to getGEO with GSEMatrix=TRUE but it does not give an ExpressionSet as output.
