Issues with getURL and xmlToList

Could someone please try the code below on your side?

url <- getURL("")
xml_file <- ldply(xmlToList(url), data.frame)

I get the errors below:

url <- getURL("")
Error in function (type, msg, asError = TRUE) :
error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version
xml_file <- ldply(xmlToList(url), data.frame)
Error: XML content does not seem to be XML: ''

It looks to me that there is something wrong with my R Studio because I cannot use getURL at all, nor some other functions. I have installed the required packages and I also loaded the libraries.

Please help. Thanks so much.
