Rstudio v1.1.456 rpubs upload error, no login prompt

RStudio IDE

Thanks for the report. I get a similar though not identical error in RStudio 1.1.463:

Error in function (type, msg, asError = TRUE)  : Empty reply from server
Calls: <Anonymous> ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Timing stopped at: 0.041 0.009 0.999
Execution halted

but it works with no problems on RStudio 1.2.1114.
