An Issue with quantmod

I am using version 3.4.2 of R and I run the following two commands:
 ???? library(quantmod)
 ???? x=getQuote( "XOM" )
and get the following error messages:

Error in 
download.file(paste("https://finance.yahoo.com/d/quotes.csv?s=",? :
 ? cannot open URL 
'https://finance.yahoo.com/d/quotes.csv?s=XOM&f=d1t1l1c1p2ohgv'
In addition: Warning message:

 ? cannot open URL 
'https://finance.yahoo.com/d/quotes.csv?s=XOM&f=d1t1l1c1p2ohgv': HTTP 
status was '403 Forbidden'

What should I do?
