I'm running an RSelenium browser in R. I had code written for it that was working completely fine until I tried to run it yesterday. Now, when I try to start a browser with rd = rsDriver(), I get the following message:

And then nothing else works. I don't understand because the code was working fine 2 days ago. Any help would be greatly appreciated! Thank you!

  • RSelenium is working OK for me, although I did just have to manually allow firewall access after a Java update on my system earlier today (Win10). If you are running from a batch file, that might trip it up. – Andrew Gustar May 11 '18 at 19:39
  • I gave RStudio firewall access, and I'm still receiving the same error. I have tried using all of the browsers. Could it be the port that I am using (4567)? – JeffJones May 16 '18 at 19:10
  • Might be worth a try. I usually use port 4444. I think it is Java that needs firewall access rather than RStudio - it worked OK once I had run my batch script manually and accepted all the firewall warnings. – Andrew Gustar May 16 '18 at 20:33
