Operating System Windows 7 Professional R version 3.3.3 Expected behaviour I would expect rsDriver to be able to have the chrome server running after the following commands: library(RSelenium) library(httr) set_config(config(ssl_verifypeer = 0L)) rD <- rsDriver(verbose = FALSE) rD Actual behaviour But I continued to get the SSL errror even after disabled the SSL verification "Error in open.connection(con, "rb") : Peer certificate cannot be authenticated with given CA certificates" Any help is appreciated!
